TUV Rheinland has approved Parker Hannifin’s high-pressure Phastite tube and pipe connection system to the ISO 19879 hydraulic applications standard.

The scope of the ISO 19879:2005 standard is ‘Metallic Tube Connections for Fluid Power and General Use – Test Methods for Hydraulic Fluid Power Connections’.

Phastite is a simple assembly concept for high pressure connections up to 1,379 bar (20,000 PSI) that can reduce installation costs compared with welded or cone-and-thread fittings.

TUV Rheinland performed pressure tests at 1.5 times the Phastite rating, leak and vacuum tests and cyclic endurance.

ISO 19879 is important for applications in the oil, gas, petrochemical, power and marine industries.

Parker has a portfolio of Phastite fluid connector sizes and shapes for metric or imperial tube or pipe applications up to one in/25mm.

Phastite fittings employ a compression assembly principle, which uses a novel form of toothed profile to make the seal.

The fittings are supplied as one-piece components.

To make a joint, the tube should be inserted before the collar is pushed along the fitting body until it reaches a dead stop.

This operation can be performed by a simple handheld hydraulic tool and takes seconds.

Phastite’s sealing mechanism is based on a series of defined internal ridges that create a secure seal, by radial compression, without weakening the tubing surface.

The ridges effectively grip in a way that retains all of the tubing’s strength.

These profiles make the fitting suitable for vibration-prone environments.
