    Rubber for old ('70s) Silca brass floor pump head

    I was rummaging around in the garage the other day and I found a '70s Silca brass pump head for one of their floor pumps. This part pretty well brackets my whole cycling carreer. Rubber is still pretty soft, but I think I'd like to replace it. Who carries those?
    I'd like to put this on a nice floor pump and dedicate it to presta valves.

    I believe they are readily available, even on Amazon. Do a google search.

    Yeah...saw that one. The ad didn't have much info about size. I have one of the big brass ones that are about 3cm outside diameter. I know Silca makes several sizes.

    Didn't know about the size issue. Often wondered but all the parts purchased fit for me. Colorado Cyclist parts has some too. You could call to make sure they have the right parts. The Silca web site is in Italian for some crazy reason! Bike Tires Direct also has the washer. This is the only one I have ever seen. What other sizes have you run into?

    the big one you need is the art. 24.1 washer
    http://www.biketiresdirect.com/produ...-rubber-washer (too bad but it's out of stock, here)
    the smaller "plug" washer fits the combo presta/schraeder reversible head
    All the washers last much longer if you use them on smooth (unthreaded) presta valves...the threaded stem valves will tear up the rubber, over time.

    Good to know, but it's out of stock. I just found my Silca pump in storage after many years. The plunger gasket is probably toast. If I can't find one, I can make one, because it's made of leather. The pump looks like heck now. I guess I oughta have a restoration thread for it!

    Indeed. I'd love to find an old one and do just that.

    Wow, thanks!!! I'll order one as soon as they are back in stock.

    Just took delivery of two leather plungers. My pump was fairly new but the leather "folded" over itself and when it hit 95psi would blow by. I really like the floor pump and both Imperial pumps I have.

    EVT makes a cast urethane washer for (some) silca heads. It even has the thread pattern cast into it. I haven't used it, but it looks good.

    I have parts for these. I picked this up on eBay several years ago:





    Otherwise, BikeToolsEtc also carries them:

    I'd just buy a modern pump head for $10 from Problem Solvers and be done with it. When it comes to tools I'm not a retro-grouch.

    As for pumps....If I can't find a nice old silca in my price range, what else is out there that is simple and bombproof? I presently own a Serfas and it works....but the cheesy plastic and thin wall aluminum make my skin crawl every time I use it.
    There is no reason why a pump shouldn't last an entire cycling career. If ine Silca floor pumps are the Campy Nuovo Record of pumps...what is the Suntour Superbe of pumps?

    A pump is nothing but a tube and a plunger with a one-way valve built in. It's used for putting more air into tires to increase the pressure within. It doesn't have to be complicated. Thin plastic tubes work just fine most of the time, as do simple metal plungers and plastic/rubber/leather seals.

    it's just a pump. If it is a portable pump then weight, size, and operability are all important considerations. But for a floor pump my singlemost important need is that it be able to put air into the tire. It doesn't need to be more complicated than that. I love mechanical things and well-designed works of engineering art. But we can go overboard here. It's not always about the bike (or bike accessories.)

    I own more pumps then I can count...I like to have spares and I like having a tool right at hand wherever I happen to be working on a bike. Many of my pumps are Silca floor pumps, and despite some complaints I'd make about their small, uncomfortable "oval" plastic handles and small unstable bases (both things that can be modified for the better) I REALLY appreciate one major feature of these pumps: they are not obsolete and are not going to become unrepairable anytime soon.
    I cannot say the same for many of the other brand pumps I have owned and currently own: once something breaks that can't be replaced (not taking about a hose or head) they are junk plastic, headed for the landfill.
    This, to me, is not just bad industrial design, but bordering criminal.

    I had a Silca pista floor pump, but somewhere along the line it got lost & I replaced it w/ an older Silca MTB floor pump. Puts out more volume of air per squeeze. Works Great...! Modern versions are available for $61

    This. For certain things (computers) planned obsolescence (SP?) is probably not a bad feature; the technology is progressing so fast that within five or so years, a it may not be able to handle what's coming at it. Pumps (and bikes in general) are not like that.
    Bicycling is not just the ride...or the bike. It's everything that comes together to make up the entire experience. Good quality tools is a part of that experience.

    As a matter of fact, I just replaced the leather washer on mine. Check Amazon for parts, they have both sizes of pump head rubber parts as well. There were three or four sellers, and the price did vary quite a bit.
