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.
Polyethylene piping MDPE, LDPE and HDPE, PN 6.3 and PN 10.
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.
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).
99% = 750 mm Hg
Max. working temperature: Same as that appropriate for the piping.
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 TA.
All bodies have pipe threads, which can be used as pipe connections.
