Pipe-fitting with adaptor assembly and related methods

摘要

A pipe-fitting adaptor assembly connectable to the coupling end of a pipe fitting is provided for reconfiguring existing pipe fittings with alternate pipe coupling ends. The fitting adaptor assembly has a tubular receptacle member configured to fit over and seal against an insert member of the fitting. A sliding retention ring carried along a ramped section of the fitting insert member interlocks with an opening formed in the sidewall of the receptacle member of the fitting adaptor assembly, such that decoupling forces tend to expand the locking ring further into the sidewall opening of the fitting adaptor assembly. The fitting adaptor assembly has a coupling end configured differently than the insert member for connection to otherwise incompatible alternative pipe sizes and/or pipe coupling configurations.

1. A pipe fitting and adaptor assembly, comprising:
a pipe fitting having a pipe insert member; an adaptor receptacle member having an open end for receiving at least a portion of said pipe insert member therein, said receptacle member being configured for connection in fluid communication with said pipe insert member of said pipe fitting; an adaptor coupling member connected in fluid communication and formed integrally with said receptacle member, said adaptor coupling member being configured as a coupling-pipe insert with a moveable retainer for connection to an end portion of a pipe that is incompatible for connection to said pipe insert member; and a retention member disposed between and interlocking said pipe insert member and said receptacle member together when at least a portion of said pipe insert member is received within said receptacle member, said retention member being movably carried by said pipe insert member apart from said receptacle member and being movable relative to said pipe insert member and said receptacle member.
