Stainless Steel Compression Fittings


How It Works

GripSeal stainless steel compression fitting image The basic principal is a simple one: the inclined plane and wedge are employed to close two collets so tightly on the outside diameter of the pipe that acting as one they can compress a seal at the pipe terminals. Here's how its done: pipe cut to length is inserted into the loosely - assembled Jaeco Grip-Seal Fitting until the pipe ends rest against the Teflon seal. The union nut is then tightened on the body threads, sliding the collets forward on the pipe until they meet the Teflon seal. As the nut is tightened, the shoulder and ring of the fitting wedge the collets so they grip the pipe.

Continued tightening forces the pipe and collet as one piece into the Teflon until it compresses and "flows" around the end of the pipe forming an impenetrable seal on the periphery of the pipe. The chamfered collets act as wedges between pipe and fitting; the greater the axial load on the pipe, the tighter the fitting grips.

Advantages of Jaeco Grip-Seal

  • Corrosion and Contamination-Proof - no crevices where fluids can stagnate or reach other parts of the fitting; fluid contacts only the Teflon seals; in the elbow and tees fluid contacts only Teflon and 316 SS.
  • Stress-Free - no cold working; no heat stress can occur.
  • Simple to Use - installation is quick and easily mastered in a matter of minutes. No special equipment required.
  • Hazards Eliminated - no open flames or arcs; welding or brazing unnecessary making them ideal for explosive environments.
  • Full Flow - Jaeco Grip-Seal Fittings have 100% full-flow area.
  • Universal - Jaeco Grip-Seal Fittings fit all pipe; even suitable for plastic and higher alloy pipes.
  • Reusable - Jaeco Grip-Seal is the only fitting with all parts reusable when pipes are dissembled for cleaning or for changing pipe system.
  • Permanent - with over forty years experience on tough installations - no reports of leakage.
  • Unbeatable Installation Cost - Jaeco Grip-Seal requires the least installation time of any fitting on the market; labor costs are only 1/5 to 1/4 of others.
  • Wide Range of Applications - Grip-Seal Fittings are excellent for quick permanent repairs, temporary repairs or prototype systems.
  • Connect - Threaded fittings, flanged fittings, butt-welded systems, tank connections and threaded valves.

Grip-Seal Fittings can join any form of piping faster, more economically, and with greater assurance of corrosion and leakage protection than any previous method of joining pipe.
