Compression coupling assembly for securing conduits together

A method of securing two conduits together end-to-end using a coupling assembly,

• a. the coupling assembly including:
• i. a compressible gland ring extending from a first circumferential end to a second circumferential end, the gland ring being:
• 1) internally threaded, and
• 2) biased such that:
• (a) there is a gap between the first circumferential end and the second circumferential end when the ring is not being compressed;
• and
• (b) the first circumferential end approaches the second circumferential end when the gland ring is compressed;
• ii. a coupling body having an internally-threaded coupling first segment extending from an externally-threaded coupling second segment;
• and
• iii. a compression nut having an internally-threaded nut first segment extending from a nut second segment, wherein:
• 1) the nut second segment includes a bend that extends inwardly at a terminus of the compression nut, and
• 2) the nut first segment is dimensioned so that it can complementarily fit about the coupling second segment;
• b. the method including the steps of:
• i. threadably engaging the nut first segment about the coupling second segment, with the gland ring positioned within the compression nut;
• ii. engaging the coupling first segment about a first conduit by inserting a first conduit end of the first conduit into the coupling first segment and rotating the coupling body, the first conduit end being externally threaded complementarily with the internal threading of the coupling first segment to allow the coupling first segment to be screwed about the first conduit end;
• and
• iii. inserting a second conduit end of a second conduit into the nut second segment and rotating the compression nut about the second conduit to engage the gland ring about a second conduit end, the second conduit end being externally threaded complementarily with the internal threading of the gland ring, wherein the gland ring is compressed about the second conduit end as the nut first segment threadably engages the coupling second segment to squeeze the gland ring between the bend and the coupling second segment.

A coupling assembly for securing two conduits together end-to-end,

• a. the coupling assembly including:
• i. a coupling body having an internally-threaded coupling first segment extending from an externally-threaded coupling second segment;
• ii. a compression nut having an internally-threaded nut first segment extending from a nut second segment,
• 1) the nut first segment being threadably engageable about the coupling second segment, and
• 2) the nut second segment having a bend that at least partly extends inwardly;
• and
• iii. a compressible gland ring extending from a first circumferential end to a second circumferential end, the gland ring being:
• 1) fittable within the compression nut second segment;
• and
• 2) internally threaded;
• b. wherein the assembly is configured to secure a first conduit to a second conduit such that:
• i. the nut first segment is threadably engageable about the coupling second segment;
• ii. the coupling first segment is engageable about a first conduit end by inserting the first conduit end into the coupling first segment;
• and
• iii. when the gland ring is situated within the compression nut, and when the second conduit end is inserted into the nut second segment, threadably engaging the nut first segment about the coupling second segment:
• 1) compresses the gland ring about the second conduit;
• and
• 2) grips the gland ring between the coupling second segment and the bend in the nut second segment.
