I bought new EDPM belts from Austin Seal Co, Inc, 9400 Business Drive, Austin, TX, 78758

I got two for my Prime in late 2017 and they are still fine. These were a custom order but very reasonable. My invoice says they are spliced, but I can’t see it. Keep in mind that they are made for high pressure conditions and chemical resistance so I’m not surprised the quality is very high. Mine were 0.070inch CS (cross section) X 296MM ID. I think these are a bit smaller CS than VPI buna belts. Your ID may need to be different and a speed controller is highly recommended. I’m not using one, but even run two of them on a standard pulley. The adjacent grooves are so close speed wise that I don’t think it makes much difference. Of course it’s a compromise, but what isn’t?
Give them a call, they are nice people and willing to help. My order took about a week to get.


Would you happen to have the part number?

Anthem MRX720, Rogue Atlas Magnum II, Sierra Towers w/ RAAL, Rythmik E15HP,

Madrac,
Custom sizes have no part number. However, their order number on my invoice is 18463. I listed the exact belt size in my original post below to help anyone ordering. It’s based on the Austin Seal measuring method that should be standard in the industry. The size I listed is for a Prime with outboard motor.
Hope this helps.

Thanks, Mr-Putty.
I believe belts are the same for Prime & Classic...I went ahead and ordered a couple to try out as not too expensive.

When you get them, gently stretch them in different areas to give them some relaxation. Before putting any on the pulley. Let us know what you think, please.

Will do. I'll try them before swapping out my current metal arm for the 3D one I just got a few days ago.

Brent you were right this is a superior material and it’s way more stable than the original VPI.
They are very stable and after installation they do not present any surface anomaly or any hump thus the speed is very stable.

This is the cheapest and best tweak ever made.
I have now a stock of 100 belts, I can change every week :lol:

VA, have I ever lead you astray ;) Glad it worked out for you. I thought I had a lot of replacement rim drive belts which numbers in the 30's. BTW, I change my rim belt every 6 months for the simple reason that I have a ton of them.

VA

I am totally intrigued, having just done the 3 belt HRX pulley upgrade and heard a significant improvement.

Could you post the part number your ordered? I find the German website a bit opaque.

Thanks much
