Wil-loc Flange Fittings are manufactured to ASA 150 patern specifications. Gaskets should be used when mounting the flange fittings to a pump. If your pumps require other flange types or sizes, please contact your Wil-loc representative or dealer.
Wil-loc Increasing Flanges allow quick connection of high flow pumps to larger discharge lines. Higher flows can be achieved because larger diameter pipe decreases friction losses.
