High Pressure Equipment Company has developed the Taper Seal line of products to assure safe and easy plumbing through 15,000 psi. These needle valves, fittings, line filters, check valves, safety heads, rupture discs and tubing are engineered and manufactured to the highest standards of repeatable quality. The reliable performance of these products has made HiP one of the world's leading suppliers of elevated pressure components.

The Taper Seal is a compression type tube connection that is extremely easy to use and re-make. The sleeve clamps onto tubing much like a machine collet for a safe and reliable connection. Taper Seal valves are available in 1/16", 1/8", 1/4", and 3/8" O.D. tubing sizes and five patterns to satisfy widely varied requirements. A line of fittings is available to facilitate adapting to Medium Pressure or High Pressure systems.

High Pressure Tubing
Tubing is cold drawn, seamless, and is supplied in the
1/8 hard condition (not annealed). Tensile strength is approximately
40 percent higher than that of annealed tubing. All tubing is manufactured in strict accordance with High Pressure Equipment
Company specifications to insure tolerances and bore quality. Tubing is stocked in lengths of 18 to 22 feet but may be ordered
in shorter lengths with no additional cutting charge.
Note: The 1/16" and 1/8" O.D. tubing sizes may be coiled for shipment. Larger sizes must
be shipped in straight lengths.
