Aftermarket replacement part — not a genuine OEM part. The squeegee blades and rubber parts on this page are aftermarket replacements made to fit Tennant machines. They are not genuine Tennant parts, we are not affiliated with or endorsed by Tennant, and brand names, model names and part numbers are used for fitment reference only. Confirm dimensions against your own sample or drawing before ordering.
The Tennant T500E decides the shape its blades have to be. The site decides what those blades should be made of. That split is the part most buyers collapse, and it is why the same machine gets the wrong compound ordered for it year after year.
Buying logic usually runs on the machine: this model takes this blade, so reorder it. The better question is what is destroying the rubber on this floor. The same machine on sealed vinyl in a school corridor and in a food plant is not the same specification, even though the profile is identical. This page works from that direction — what kills the blade, then which grade survives it.
Start with the failure, not the catalogue
Read the worn blade before you reorder. What it looks like when it comes off tells you which mechanism did the work, and each mechanism points at a different compound.
| What you see on the worn blade | What caused it | What to change |
|---|---|---|
| Evenly rounded lip, blade visibly shorter, fine dust in the recovery tank | Sliding abrasion from grit | Harder compound with better cut and tear resistance |
| Swollen edge, tacky or spongy surface, wavy lip that never got thin | Oil, grease or solvent-based cleaner attacking the rubber | Oil-resistant compound, or a change of detergent |
| Hardened, cracked or checking surface, loss of flexibility | Heat: hot water, steam cleaning, or hot wash-down cycles | Compound chosen with the temperature range in mind, plus a cool-down before parking |
| Flat spot or curl that stays after fitting, pickup lost at one point only | Compression set from being stored under load or parked on the lip | Fix storage and parking habit; check the hardness suits the duty |
That last one is worth pausing on, because it costs money out of proportion to how often it gets mentioned. A blade left resting on its lip between shifts takes a set, and no grade change brings the edge back. Rotating or lifting the assembly between uses is free.
If the symptom is a streak that returns in the same place with fresh rubber fitted, the cause is usually upstream in the setup rather than in the material — frame not level, too much down-pressure, a blocked recovery path, or a worn caster. Our replacement cycle guide covers how to plan around wear versus how to chase a fault.
The three grades, and where each one stops making sense
We supply three compounds. Each has a range where it is the right answer and a boundary past which it costs more than it saves.
- Natural rubber, 65 ± 5 Shore A. The default for smooth tile, vinyl and sealed epoxy. It conforms well to a flat floor and gives the cleanest pickup, which is why it stays the volume grade across most commercial sites. Our red rubber sheet for squeegee blades page covers the base material.
- Cast polyurethane, 85 ± 5 Shore A. Rough or damaged concrete, expansion joints, oily and greasy surfaces, anywhere cutting and tearing rather than even wear is what ends the blade’s life. Higher cost per set, usually recovered in labour and downtime on abrasive floors.
- Economy gum rubber, 45 ± 5 Shore A. Light duty on smooth floors where the buying decision is price-led and the area is small. It wears faster on anything coarse.
Hardness is measured by the ASTM D2240 durometer method, and compound classification across batches is framed by ASTM D2000. Naming both methods in an enquiry takes two lines and removes most of the room a supplier has to wiggle. A quote offering a bare “65 Shore A” with no test method, or promising a tolerance tighter than ±5 Shore A, is describing a laboratory coupon rather than a production batch. Ask for readings taken off production pieces.
The full trade-off, including where each grade stops paying for itself, is in our material comparison. One warning deserves repeating because it causes more returns than any other spec error: harder is not automatically better. On smooth, polished floors a hard blade chatters instead of sealing and leaves a haze, and adding down-pressure does not cure it.
Why polyurethane is not a free upgrade
Polyurethane generally lasts longest on rough or oily floors, and that single fact has quietly turned it into a default recommendation it does not deserve. It is more sensitive to temperature and operating conditions than natural rubber. Hot wash-down areas, machines that sit in direct sun, and sites that clean with hot water all narrow the advantage, and on a smooth floor there was no advantage to start with.
Sell it with that caveat attached rather than as a flat upgrade.
Service life in normal commercial duty is typically two to three months per blade, an industry figure rather than a guarantee. It moves with cleaning frequency, detergent concentration, water temperature and floor condition, and a machine working two shifts a day will sit at the short end of that range. Budget for replacement on a cycle rather than reacting to a complaint.
Specify it so the second shipment matches the first
Most disputes in this category are not about bad rubber. They are about two parties agreeing on a description that was never precise enough to be met twice. Four things belong in the specification:
- Durometer with a test method and a range — 65 ± 5 Shore A to ASTM D2240, not “65 Shore A”.
- Profile verified against a physical reference — the worn blade, its measurements, or a drawing. We work from a sample or drawing rather than a published chart: production runs and regional builds vary, and we would rather say we cannot confirm a dimension than ship a guess. Anything unverified goes back to you before tooling is cut.
- The set definition — one set is one front blade plus one rear blade. The rear carries the vacuum seal and decides whether the floor dries; the front takes the debris load. On most machines they wear at different rates, so name the split when you request a quote.
- Quantity per style — the unit the pricing is built on.
Our cross-reference guide lists the models and brands we already hold tooling for. If the T500E units you service run an aftermarket or revised frame, treat it as a new profile and send a sample rather than assuming it matches the book.
Leaving a floor wet is not a cosmetic failure. Under OSHA 1910.22 walking surfaces are expected to be kept in a safe condition, and the blade is the cheapest line in that risk.
MOQ, tooling and mixed orders
- MOQ 20 sets per style on a profile we already hold tooling for.
- USD 60–120 tooling for a profile we do not hold, waived once cumulative volume reaches 500 sets.
- Mixed orders allowed, USD 3,000 minimum order value, so one container can cover a dozen models rather than committing the whole budget to one profile.
For distributors the margin generally sits in the spread against a captive OEM parts channel, not in grinding unit price; that argument is set out in OEM vs aftermarket squeegee blades. For end users the number worth comparing is cost per cleaned hour, since a blade that streaks costs a re-clean.
Where you serve sites with genuinely different floors, run a 20-set trial in each grade instead of standardising on one. Two lines tells you within a month which compound belongs on which site — and that answer holds for every machine on that floor, not just the T500E.
Samples, and how claims are handled
Samples are chargeable, not free, and take 7–15 days to prepare and ship. Most importers buy one set for one machine, run it for a few weeks, then place the volume order against a grade proven on their own floor.
Settle the claim rules while the order is still open, because blade complaints surface at goods-in, weeks after manufacture:
- Claims raised within 7 days of receipt, counted from delivery, not dispatch.
- Only the defective pieces are replaced, not the whole batch.
- An unboxing video is required, filmed from before the carton opens and close enough to show the defect.
- Freight on replacement pieces is on the buyer; most consolidate it into the next shipment.
Coverage is for manufacturing defects: damaged or feathered edges, wrong dimensions, defective material, hardness outside the agreed range. It does not cover ordinary wear, fitting damage, or early wear caused by specifying the wrong compound for the floor.
Request a quote or a sample set
Send us the machine model, how many units you run, your floor types, what detergent you use and whether you clean hot. We will confirm the profile against a sample or drawing, recommend a grade for those conditions rather than a default, and quote a 20-set trial in each candidate compound so you can settle the question on your own floor. Request pricing or a sample set and we will come back with lead time and freight options.
