Strainer Screen and Cylinder Co. Inc. is a manufacturer of heating, plumbing and pump/motor replacement parts and accessories. We have been making parts for the heating and plumbing industry since 1971. We sell to authorized wholesalers and rebuilders only. We do not sell to Service Companies, the trade or to the general public. This is the reason we require a password to enter our complete web site. We do not want the trade and the general public to view our prices. We have extensive listings of gaskets and pump replacement parts-perhaps more than any company in the Heating Industry.
