    Pump Head Gasket

    Yesterday I flatted. When I installed the new tube, I began pumping with my Silca frame pump. (it has a campi head.) After about 20 strokes, air started coming out of the head, rather than into the tube. I know that they have not made Campi heads for many years. Can anyone think of a way that I can find a replacement gasket for this head. Though it has sentimental value for me, I would consider replacing it with a different pump. Recommendations would be appreciated.

    Are you talking about the gasket that's between the head and the pump? If so, I found a replacement rubber washers at Home Depot. They are a little thinner than the original but it works.

    Pump Gasket

    I am referring to the gasket in which the valve is inserted.

    Did you check their website perchance?

    The Obvious

    As I mentioned, it is not a Silca head, it is a Campi head.

    Campi Pump Gasket

    Thanks:
    It is the gasket that the valve goes into.
    I think that it would be better jutst to buy a new pump;
    I am thinking of the Blackburn frame fit pump

    Eraser Head

    Is this the type of pump head you have? If so, any bike shop worth it's weight in salt should have a replacement basket for you. They're cheap. I usually buy a couple (just in case).

    What does the inner rubber part look like? You could probably modify a silca part to fit, Or I might have one but don't know what it looks like. I bet those heads have not been available other than NOS for 20 years.

    Except for the chamfered top edge, it's a straight-sided rubber plug, 15 mm diameter x 6.4 mm thick, with a 5 mm diameter, top-chamfered hole. If you can't get the Campagnolo-embossed original gasket, I'd try Lowe's or Home Despots "Specialty Fasteners" section, in the "rubber plugs, stoppers, washers, spacers" drawers. Might have to drill a 5 mm hole, but that's no biggie.

    Packing a thin washer on top of the gasket and screwing down the hold-down nut tightly will compress the gasket some more. With the rubber nowhere else to go, the worn-out hole sometimes closes up enough to be good for another 10 years of Silca Impero pumping pleasure. Worth a try.

    The gasket in my old Campy pump heads actually have a reduced diameter at the bottom, which I think your picture shows. The rubber sits in the female side of the pump head, and the shoulder of the larger diameter section keeps it from just falling into the head. That's how mine are, anyway. And they are larger diameter than the standard Silca gaskets. Short of finding one at a bike shop, I would agree that a hardware store would be the place to start, and you could shape whatever you found so it would fit the Campy head.

    My gasket does have the slightly reduced diameter at the bottom you observed. But I'm almost sure that in my case it's just an imprint of twenty years of confinement in the 1.8 mm deep part of the pump head. I think with the hold-down nut (or collar) tightened and then re-tightened many times, the upper part of the gasket expanded slowly over the years to fill the slightly larger diameter of that hold-down nut. With my pump head, the gasket has no way to fall into the head further than 1.8 mm because it rests on the pressed-in washer.

    Too bad about the rust Twenty years of rain, sweat and a plethora of useless, but corrosive, "sports drinks."

    Thanks for the pictures and the trip in THE GOBACK Machine. Actually, I hated Silca frame pumps back then and nothing has changed my mind yet.

    Even now they are light weight, rock solid, 10x better than any mini pump, and you can paint them to match any color scheme. The only down side is the inability to reach pressures above 80psi. But which would you rather have when you flat miles away from home? An 80psi pump or none at all?

    Silca Impero=piece of mind.

    You are absolutely, 100% right! I wasn't thinking about that when I took apart a Campy pump head, and just saw that indentation. I took two of them apart, and your description of the situation is right. My bad!
