1.1 This specification covers a Modified Stub ACME Thread Joint with an Elastomeric Seal used to seal the joint components in plastic piping components, or (if applicable) to components made of other non-plastic materials used for plastic piping components used in turf irrigation systems.

1.2 This specification establishes requirements for dimensions and gauging of Modified Stub ACME Thread and Elastomeric seal.

1.3 Tapered pipe threads are not covered in this specification.

Note 1—The terms “bottom out ” and “back off” are used to imply complete engagement of the threaded connection and un-threading of the connection and do not imply using a pipe wrench or other tools which would damage plastic pipe and fittings.
