Rotary shaft seals

I needed to oversize my trailer oil seals and found an imperial size that translated to exactly what I needed (Lucky!)
Anyway only available in Viton and fairly expensive from the various suppliers out there Fortunately I found Wych who also do them in the Viton and the cheaper Nitrile rubber option!
They arrived the next day. PDQ!
The fit was perfect.
The quality is very good.
Wych were the only supplier who had the nitrile option !
So 100% to Wych bearings on my first order.
Looking at the inventory of items I will be a returning customer very soon as I have many on going projects that require these sorts of parts.
Thank you Wych.

I bought these to replace seals on an American made mower whose parts we seem to be charged n arm and a leg for while in America they're dirt cheap. However, these took a little finding but they're the correct size (imperial) and more importantly they fit and were a great price. Would recommend as there is so much choice .
