High Pressure Fluid System Components

PAC Stainless supplies the tubing and accessories that are required for high pressure applications. Medium Pressure (up to 20,000 psi), High Pressure (30,000 through 60,000 psi), and Ultra High Pressure (100,000 through 150,000 psi) solutions are offered for tubing, valves, and fittings. Tubes are provided at random lengths between 20' and 25' long and are available in 304, 316/L, and 317L grade stainless steel. DK-Lok high pressure series valves and fittings are made of 316 cold-worked stainless steel and are a cone and thread design available in multiple configurations. PAC Stainless has the material for your high pressure applications under control.

Mechanical Properties and Fabrication:

The high pressure product line consists of special property combinations (available on request) to create unique tensile, yield, and elongation characteristics in the 1/8 hard condition. The tubing is bright annealed during the process, omitting the last production pass. A cone and thread tool can be used to prep the tubing for fitting and valve installation and is available for purchase.
