Abstract
A fitting for the connection of pipes includes a body (10) having a rubber holder (11) and accommodating two toric seals (13, 14) spaced in parallel to one another, and the pipe to be connected to the fitting is threaded onto the rubber holder and is locked there by an outer pressed bushing (17). A third toric seal (15) is mounted on the rubber holder for sealing between the rubber holder (11) and the pipe connected thereto.
Claims12
A pipe press fitting for connecting plastic, multilayered and rubber material pipes, the fitting comprising:
- an outer bushing;
- a body including a rubber-holder section with a first groove outer surface and a second groove outer surface spaced in parallel to said first groove outer surface, a corrugated section for threading the body rubber holder section to a pipe and locking the body rubber holder section to the pipe in cooperation with said outer bushing that is shaped by means of pressing;
- toric seals spaced from one another along a longitudinal axis of said holder section and each of said toric seals lying in separate parallel planes, said toric seals being seated in said first groove outer surface and said second groove outer surface respectively;
- and
- a third toric seal for the sealing between the said rubber holder section and the pipe connected thereto, said third toric seal rotatable with respect to said holder section under compression by said outer bushing.
A press fitting for a pipe, the press fitting comprising:
- a body including a holder section insertable into an end of the pipe, said holder defining a plurality of annular seats;
- a plurality of toric seals, each of said plurality of toric seals being positioned in one of said annular seats;
- an outer bushing positionable around the end of the pipe when said holder section is positioned in the end of the pipe, said outer bushing being compressable around the end of the pipe to seat the pipe to said holder section, one of said annular seats and a corresponding said toric seal being non-rotatably held on to one of said holder section and the pipe by compression of said outer bushing, another one of said annular seats and a corresponding another said toric seal being rotatable with respect to one of said holder section and the pipe by compression of said outer bushing.
A pipe connection comprising:
- a pipe having an end;
- a body including a holder section inserted into said end of said pipe, said holder defining a plurality of annular seats;
- a plurality of toric seals, each of said plurality of toric seals being positioned in one of said annular seats;
- an outer bushing positioned around the end of the pipe with said holder section positioned in said end of said pipe, said outer bushing being compressed around the end of the pipe to seal the pipe to said holder section, one of said annular seats and a corresponding said toric seal being non-rotatably held on to one of said holder section and the pipe by compression of said outer bushing, another one of said annular seats and a corresponding another said toric seal being rotatably held with respect to one of said holder section and the pipe by compression of said outer bushing.
