  • Plumbing and heating piping
  • Industrial piping
  • Water system installations
  • Plumbing and heating repairs

Our unique K700 clamp style fitting “bites” the pipe to hold greater pressure and resist pipe pull-out in general piping applications.

Telsco K700 Series Fittings are suitable for fast, easy installation or repair of most IPS plastic pipe. Metal insert stiffeners should be used to support the pipe wall.  Fittings are not recommended for thin wall notch sensitive tubing.

700 and K700 SERIES GENERAL SPECIFICATIONS

  • Coupling and adapter bodies, 1020HR steel tubing
  • Tee and ell bodies and end nuts, malleable iron Grade 32510

WARNING - System Designer and/or Contractor must provide suitable anchoring of piping to prevent pull-out from fittings when applications subject piping to external forces such as ground shift and temperature variations that cause linear pipe contraction.

Telsco fittings are suitable for use on water and oil and carry a limited warranty to give satisfactory service when recommended pressures are not exceeded and when fittings are installed per torque specifications.

Described below are the recommended assembly procedures for Telsco Series K700 compression fittings.

Burr Removal - To facilitate assembly, any internal and external burrs are to be removed from the cut-off ends of the pipe. Remove cutting chips from inside of pipe.

Stiffener Insertion - A metal Stiffener is required to be inserted within the polyethylene pipe for support of the pipe wall. Caution must be exercised in using the correct Stiffener size that matches the pipe or tubing (wall thickness) being joined; example, SDR11. Insert Stiffener full depth within pipe to its flange stop.

Cleaning - Clean exterior surface of pipe of all foreign matter such as dirt and compounds to insure a good sealing surface for the fitting gasket. Inspect inside surface of gasket and clean if required as accumulations may result from storage conditions and handling.

Pipe Insertion - Piping is to be inserted within the fitting to maximum depth:

  • Couplings - midway
  • Elbows - to stop
  • Adapters - to stop
  • Tees - to outlet

To achieve maximum pipe pull-out resistance and sealing, End Nuts are to be wrench tightened per the following table. Use recommended wrench size and apply body pressure to approximate listed torque.
