Plastic pipe couplings

This plastic pipe coupling is suitable for PEL, PEH and PEM pipes and can be used both above and underground. Its impressive list of features includes injection-moulded acetal plastic trust screws with UV stabilizer. Resistant to sunlight, these ensure more reliable, trouble-free operation. For easier maintenance, the PRK can be dismantled and reassembled.

Key features

Comprehensive and flexible range

Ensures rapid installation.

No loose parts

A near-single unit construction allows for quick and easy installation.

AMETAL® construction

Dezincification-resistant alloy that guarantees a longer coupling lifetime, and lowers the risk of leakage.

Technical description

Application:

Polyethylene piping MDPE, LDPE and HDPE, PN 6.3 and PN 10. NOTE: Use reinforcing bush (liner) for MDPE pipe PN 6.3 and PE 80/100 pipes.
The pipes must be cut in 90° angle, preferable a pipe shears, and remove any burrs before mounting.

For PVC pipes with special thrust screw and cone, see Accessories.

PRK-coupling with FPL thrust nut for soft and hard copper pipes and soft steel pipes. A support bush must be used for soft copper and steel pipes. See catalogue leaflet FPL for complete details.

Dimensions:

16 to 63 mm
Special couplings not included in the standard range can be produced by means of reductions.

Max. working pressure:

Same as that appropriate for the piping.
(Coupling max 1.6 MPa = 16 bar).

Max. vacuum:

99% = 750 mm Hg

Temperature:

Max. working temperature: Same as that appropriate for the piping.

Material:

Body: AMETAL® or red brass (allows underground installation).
Thrust screw: Acetal plastic
Thrust screw for dim 63, of AMETAL® with cone of Acetal plastic.


AMETAL® is the dezincification resistant alloy of IMI Hydronic Engineering.

Threads:

All bodies have pipe threads, which can be used as pipe connections.
