Push-fit fluid connections to larger bore sizes

Parker Instrumentation has extended its range of 'push-fit' fluid connectors for high-pressure industrial applications, adding eight new variants to allow the 20,000 psi (1,379 bar)-rated connector to be used on larger metric and imperial tubing sizes of 14, 16, 18, 20, 22 and 25 mm, and ¾ and 1".

Assembled by means of a simple push-fit operation, Parker Instrumentation's Phastite connectors provide permanent connections for high-pressure fluid systems. For permanent connections, and these elevated pressures, system builders would typically use either welded or 'cone and thread' style fittings, which are time consuming and expensive to install. Compared with these products, Parker Instrumentation's Phastite connectors can reduce installation costs by a factor of 90% or more.

Phastite employs a compression assembly principle using a form of toothed profile, which makes the seal. To make a joint, all that's required is to insert the tube and then push the collar along the connector body until it reaches a dead stop. This operation is performed by a simple hydraulic tool and takes a few seconds.

This assembly approach contrasts with the requirement to perform a 360° weld around the circumference of a tube, or the coning and threading of a tube end to prepare it for use in a special screw-together fitting, operations that again require skill and time - in some cases up to 30 mins or more.

The Phastite range now includes straight union, union elbow, 'tee' and union cross connector shapes in imperial and metric sizes from ¼ to 1" and 6 to 25 mm.
