PRK

Plastic pipe couplings suitable for PE pipes

This plastic pipe coupling is suitable for PE pipes, SDR 11 and SDR 17, of material PE40, PE80, PE100 and PE100RC, 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.

Features and Benefits

Comprehensive range

For optimum flexibility and faster installation, the FPL is available in a Dy range of 8-28 mm.

Complete or components

For ease-of-maintenance, the FPL is available as a complete coupling or as individual parts.

AMETAL^®

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

Applications

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

Polyethylene piping, SDR 11 and SDR 17, of material PE40, PE80, PE100 and PE100RC according to EN 12201.

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.

NOTE: Use TA's reinforcing bush (liner) for SDR 11 20-50 mm and for SDR 17 32-63 mm. See Accessories.
