All Silca pumps employ steam pressure-formed leather cup washers to achieve high pressures and smooth action rather than inexpensive, sticky o-rings. The washers are hand-made in Milan, Italy cut from excess leather used in handbags and car interiors. The 731 is a 28 mm diameter washer, used on pumps produced from 1917-2008.

Fits 28 mm internal diameter Pista and Super Pista pumps (pre 2008).

A simple pump part that's been around for over 100 years and still works great!

These washers are so simple, yet work so well for a long time. But, there's a secret to getting that return. You must condition them for use! Just Google how to do it. But, basically you squirt some oil all over it and massage it in to the leather. One thing the video shows is turning it in side out a couple of times to stretch it and work the oil into the leather. Just remember to turn it back to right side out!. This procedure makes a big difference in how well it seals.

I needed to rehab my pump and only after receiving this did I realize that I needed a 30mm washer rather than the 28 mm washer that I ordered. The 28 mm washer is up for grabs. Let me know if you want it.

This was really easy to install and now my 25+ year old silca pump is back on action.
