Instrumentation has unveiled a radical new tube connector it claims will deliver huge cost savings to builders of industrial equipment involving fluids.
Assembled in a simple push-fit operation, the new connectors provide permanent connections for fluid systems operating at up to 20 000 psi (1380 bar). 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. In comparison, Parker Instrumentation estimates that its new Phastite connectors could reduce installation costs by 90% or more.
Phastite employs a compression assembly principle using a novel form of toothed profile to make the seal. The connectors are supplied as one-piece components. To make a joint, the tube is inserted and the collar is pushed along the connector body until it reaches a dead stop. This operation is performed by a simple handheld hydraulic tool, and takes just a few seconds.
Inside Phastite connectors is a unique sealing system, based on a collar which slides along an angled body, compressing a number of circular profiles into the tubing. At the end of the short travel is a vertical face which provides confirmation of correct assembly.
Phastite is much faster to assemble than welded and cone-and-thread fittings, yet also deskills the process,
