  • Patent number: 9909701
    Abstract: A tube coupling to receive and hold a tube includes a coupling body (10) having a throughway to receive a portion of a tube. A collet (17) in the coupling body has legs (21) with outer surfaces that engage with a tapered surface (24) in the coupling body which urges the legs inwardly to resist withdrawal of the tube. A biasing member (26) provides a biasing force without the tube inserted to urge the legs axially onto the tapered surface. The collet (17) can grip a large variety of pipe diameters. The coupling may be supplied with a number of inserts (30A-D) for sealing with the inner diameter of a pipe, the inserts having different diameters. A tool (50) for preparing the end of a pipe to receive the coupling is also contemplated.

  • Publication number: 20170307120
    Abstract: A connector includes a body having a throughway with an open end. A shoulder in the throughway faces the open end and supports an O-ring. A collet in the open end of the throughway has a plurality of legs extending into the body away from the open end, each engaging with the body and having an inwardly facing tooth to grip, in use, a tube in the throughway. The body has a plurality of fingers extending to the open end. A cap fits over the open end of the body and extends from the open end towards the opposite end. The cap has a plurality of recesses in a wall at the open end into each of which one of the fingers is retained by a snap fit. The radially inwardly facing faces of the fingers of the body incline inwardly towards the open end providing a cap angle for the collet.

  • Patent number: 9551447
    Abstract: A connector having a body 1 with a central throughway in which a tube T is received. A collet 30 within the body has a plurality of flexible legs 32 arranged to grip the tube T if a force is applied to withdraw the tube. The connector further comprises at least one first tooth 14, the first tooth having a gripping edge in a plane angled to a plane perpendicular to the main axis of the connector, and being mountable with respect to the body so as to be non-rotatable about the main axis X.

  • Patent number: 9261214
    Abstract: A tube coupling includes a body (1) to receive a tube (22). The body has lateral recesses (12) extending outwardly from an internal wall. An O-ring (3) is retained by the body distally of the recesses. A collet (5) includes a ring (6) and collet legs (7) to be received in the lateral recesses and having a tooth (8) facing the passageway. Proximal movement of the collet with respect to the body causes the fingers to deflect inwardly. A tube support (10) includes a ring (12) and has a key to align with the body. Castellations (13, 14) extend proximately from the tube support ring and are complementary to the collet legs to align the collet with respect to the body as the collet is inserted into the body.

  • Patent number: 8882156
    Abstract: A tube coupling to receive and hold a tube (T) includes a coupling body (10) having a throughway with an annular step (24) facing an open end (12). An annular seal (25) is located in the coupling body adjacent to the annular step. An end cap (13) engages the coupling body and is axially moveable. A collett (17) in the cap has legs (20) with outer surfaces that engage with a tapered surface (23) in the end cap to urge the legs inwardly to grip the tube. The seal (25) is compressed axially in response to the forward movement of the end cap (13) to cause the tube end to be pressed into sealing engagement with the seal end. A biasing member (28) provides a biasing force to urge the legs (20) axially onto the tapered surface (23) when the cap is in the retracted position.
