6000-1

With flat faced construction and a recessed O-Ring, TECH-O-SEAL pipe fittings actually create their own seal. With only light wrenching the seal never leaks, never needs retightening, yet can be easily broken and resealed indefinitely without having to replace the actual piping. From vacuum to 3,000 PSI, TECH-O-SEAL fittings are fail-safe, yet priced extremely competitively. They come in a complete family of unions, elbows, tees, and connectors for pipe sizes ranging from 1/8″ to 1-1/2″.

  • FAIL-SAFE LEAKPROOF RELIABILITY, with any pressure actually serving to strengthen the seal rather than loosening it. Good from vacuum to 3,000 psi for pipe fittings; vacuum up to 10,000 PSI for other TECH-O-SEAL valves and fittings.
  • EASY COMPONENT REPLACEMENT – the flat faced construction allows for slipping the component in and out without disturbing the surrounding tube or pipe sections.
  • NO MAINTENANCE, the seal, once made, never requires retightening.
  • RESISTANCE TO VIBRATION – the seals just won’t loosen, even under extreme vibration or pressure surges.
  • SIZE CHANGES WITH ONE FITTING are implemented through a complete line of standard parts.

Unions, Connectors, Elbows & Tees

The part numbers for all fittings may have one, two or three dash numbers to indicate size. Where only one dash number is given, the assembly has the same size at all ends. For example:

Threaded Parts

Part numbers for fittings with threaded ends always have two or three dash numbers. For example:
