There's not too much that can be said about a Urethane Pump Washer. What we can say is that you should probably grab a few of these and put them in every pump you own. We love the UrethanWasher the. you compare it to the stock rubber seals most companies use for a few reasons but it mainly comes down to durability. If you are looking for a set it and forget type deal in your inflator head, then look no further than a Urethane Washer from Efficient Velo Tools.
