1.1 This specification covers material and performance requirements for plasticized PVC compression gaskets used in the connection of residential and commercial vitreous china plumbing fixtures to 2-, 3-, and 4-in. sanitary drain lines. These type gaskets are inserted into and compress against the inside diameter of the sewer pipe, closet or urinal flange while attaching to the vitreous china plumbing fixture with a flexible adhesive. The result is a gas- and watertight seal.1.2 The values stated in inch-pound units are to be regarded as standard.
