Components: It includes a rubber seal and a polypropylene cap.
Usage: It is used in 110mm (4-inch) soil and vent pipe installations, particularly for converting a solvent weld socket to a push-fit socket.
Product Variations: While the code SWE99 refers to the type, the specific product often includes a suffix for color, such as SWE99SG (solvent grey) or SWE99B (black).
Certification: The adaptor is certified to standards like BS4514 and EN1329.
