Parker instrumentation fittings are designed as leak free connections for process, power, and instrumentation applications. The most important consideration for any application is the compatibility of the fittings and tubing material with the media to be contained. These fittings offer an extensive range of alloys in the market, from conventional steels to high nickel alloys and titanium for the most demanding applications.

Parker CPI™/A-LOK® Instrumentation Tube Fittings

Parker CPI™/A-LOK® Instrumentation Tube Fittings are designed as leak-free connections for process, power and instrumentation applications. These single and two ferrule fittings are manufactured to the highest quality standards and are available in a broad range of sizes, materials and configurations. The Parker CPI™/A-LOK® tube fitting has been specifically designed for use on instrumentation, process and control systems, analysers and environmental equipment employed in chemical, petroleum, power generating and pulp and paper plants. CPI™/A-LOK® fittings have also been used extensively in other applications and industries wherever high reliability and quality are required.

Parker 10k High Pressure

10K High Pressure Pipe Fittings

Parker high pressure pipe fitting range are designed to be used for process control connections between pipe sizes and overcomes the pressure limitations of standard industry pipe fittings. All the Parker pipe fittings are rated at 10,000 PSI, which overcomes the issue that a standard pipe fitting will have by being derated due to size and wall thickness limitations. Having the pipe fitting permanently marked with the pressure rating avoids potential installation error which means safety is an integral part of the pipe fitting. Parker’s high pressure 10,000 PSI pipe fittings are precision machined from bar stock.

Parker Phastite

Phastite® Fittings

Phastite® is a breakthrough in tube connection systems; its innovative design concept eliminates the costly requirement of welding and combines quick installation with a signal assembly process achieving a tube connector that can be used in applications up to 21,400 psi/1,470 bar. Developed in a range of standard and corrosion resistant alloys to cope with the most demanding environments, Phastite® meets all the relevant performance and functional requirements of industry standards.

Parker ISO Conversion Fittings

Instrumentation Pipe & ISO Conversion Fittings

Parker ISO Conversion Fittings are designed to the highest quality standards to allow connections between components and systems which use both NPT and ISO Thread configurations. These thread forms are used where pressure tight joints are either made on threads utilizing a thread sealant or where pressure tight joints utilize a peripheral seal on the face of the mating component.

Parker Welded Fittings

Weld-lok® Socket Weld Fittings

The Parker Weld-lok® line of permanent socket weld tube fittings provide a sturdy, tight integral line system that remains unaffected by shock, vibration or thermal distortion, meeting the most exacting requirements of any system.
