| Innovative tube fitting from Parker Instrumentation Parker Instrumentation announces a new design of tube fitting that can deliver huge cost savings to builders of industrial equipment involving fluids. The new fittings provide permanent connections for fluid systems operating at up to 20,000 PSI / 1,379 bar. Phastite employs a compression assembly principle using a novel form of toothed profile, which makes the seal. The fittings are supplied as one-piece components. To make a joint, all that's required is to insert the tube, and then push the collar along the fitting body until it reaches a dead stop. This operation is performed by a simple handheld hydraulic tool, and takes a few seconds. The tool requires no skill to use, and assures users of right-first-time connections. This assembly approach contrasts with the requirement to perform a 360º weld around the circumference of a tube, an operation requiring skill, consumables, expensive equipment, and up to 10 minutes of time. 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 this case up to 30 minutes or more. For many applications, the quality of the weld is also tested by means of dye penetration, or x-ray inspection, adding further substantial costs to the installation process. Inside Phastite fittings is a unique sealing system, based on a collar which slides along an angled body, in the process 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. The Phastite range includes straight union, union elbow, 'tee' and union cross fitting shapes in imperial and metric sizes from ¼ to ½ inch or 6 to 12 mm. There is also a range of termination connectors that provide a link between the equipment's fixed, permanent tubing, and any element that needs to be disconnected or maintained. write your comments about the article :: © 2006 Construction News :: home page |
