Custom Pump Fittings

S.I.S. offers a full line of flange fittings for all models of vacuum pumps, diffusion pumps, and vacuum systems. All fittings are made from aluminum because it's light in weight, strong, and is resistant to many chemicals. Seals can be made with Viton® O'Rings usable to 250 degrees C at high vacuum applications. In addition to the sizes, configurations and models shown, we can custom manufacture any style you need.

Hose Unions

Aluminum Hose Unions are used to splice vacuum hoses to reduce or increase size. Other sizes can be custom manufactured by S.I.S.
