3FA-14437-00
The only NBR part in this group. NBR70 is specified where the duct sees fuel or oil mist, which EPDM would not survive.

The face on this part
Moulded rubber elbow duct with ribbed flex section. It sits in the YAMAHA Rubber Parts group, and the photograph above is of the part itself rather than a rendering — what you see is the tread, the outline and the finish as they leave the tool.
With no metal face, the compound is the part
There is nothing to hide behind. A pad that is too hard makes its tread pattern useless; one that is too soft wears through at the rib tips. Send the service conditions and our designers will propose a grade rather than asking you to guess one.
How the compound is proven
Shore A hardness, density, ozone, ageing, tensile strength, elongation to fracture, vulcanization and insulation resistivity, oil resistance and Mooney viscosity — all run in the Beijing facility, next to the press rather than a week away.
Tooling and first parts
All tooling is designed and made in house. Parts from a prototype tool reach you in 4 weeks, which is the window in which the face, the retention and the hardness can still be changed without restarting anything.
Background reading
Choosing a Pedal Pad Compound: EPDM, SBR, TPE and When Each One Fails
Service conditions, not price, should pick the compound. Here is how we narrow it down and what we test to prove the choice.
Reading a Compound Code: What EP70, NBR70 and CI60 Tell You
The codes marked on our YAMAHA parts are a compact statement of family and hardness. Here is how to read one.

Four tread families appear across this catalogue. Each one is a different answer to the same question about grip and wear.
Questions buyers ask
Which compound will this part be moulded in?
Whichever the drawing calls for. We run EPDM, SBR, TPE, TPE-SEBS, PVC and PP with or without glass reinforcement; if you have not fixed a compound yet, send the service conditions and we will propose one.
How long before I see a real 3FA-14437-00 sample?
Prototype parts in 4 weeks. That window is also when design changes are cheap — our designers will suggest improvements to the part while the tool can still absorb them.
What do you need from us to quote it?
Native SolidWorks, Pro-E or UG files, or STEP. Add the volume, the duty and the delivery country and we can quote tooling and parts together.
How is the material verified?
Beside the press rather than a week away. Hardness and density catch a mis-weighed batch, Mooney viscosity catches a compound that will not flow the same way tomorrow, and ozone and ageing catch what only shows up years later.
What does the NBR70 marking on the part mean?
It is the customer's own compound designation, carried on the part so the grade travels with it. The letters give the family — EP for the EPDM grades, NBR for nitrile — and the digits give the nominal Shore A hardness.
