Phastite connectors approved to ISO 19879

Parker Hannifin's instrumentation products division has secured approval for its high-pressure Phastite tube and pipe connection system to ISO 19879 ' Metallic tube connections for fluid power and general use - Test methods for hydraulic fluid power connections.' Testing was performed by TUV Rheinland.

Phastite is a simple assembly concept for high-pressure connections up to 1379 bar (20,000psi) that can greatly reduce installation costs compared with welded or cone-and-thread fittings. High-pressure hydraulic lines are a major application, and ISO 19879 certification provides independent verification of the connectors' capability. Tests performed include pressure tests at 1.5 times of the Phastite rating, together with leak and vacuum tests, and cyclic endurance.

Parker's Sheldon Banks comments: "ISO 19879 is an important qualification for many users in oil, gas, petrochemical, power and marine industries - key markets for Phastite. We are delighted to receive this approval, which adds to independent approvals from users in areas including offshore and onshore processing facilities."

Parker has a comprehensive portfolio of Phastite fluid connector sizes and shapes for metric or imperial tube or pipe applications up to one inch and 25mm. Phastite fittings employ a compression assembly principle using a novel form of toothed profile that forms the seal. The fittings are supplied as one-piece components. To make a joint, all that is 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.

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 also make the fitting particularly suitable for vibration-prone environments.
