Alprene Compression Fittings

Components and detailed notes

Conformity to all important standards and availability in a wide range of diameters makes Alprene your first choice.

Alprene compression fittings are suitable for use with all types of polyethylene pipes PE 80, PE 100, PEX and PVC-U with special transition kit. The fitting is ready to be installed out of the box without any preparation. The pipe can be inserted directly without disassembling the fitting. There is a 16 bar resistance throughout the complete range of Alprene fittings, with approvals according to the most  stringent regulations worldwide.

The special lip gasket grants a perfect performance even with ovalised, scratched and undersized pipes.

A complete range of compression fittings allows assembly on all types of polyethylene pipes (PE HD, PE LD, PE 80, PE 100) and PEX-a with no need to disassemble the fitting. After loosening the nut, the pipe can be inserted directly to the pipe-stop (Pushfit type).

  1. The body, in black polypropylene, is designed and manufactured as a unique modular construction with axial 1. reinforcements. The production batch number is marked on the body, ensuring easy traceability.
  2. The thrust ring, in polypropylene, applies pressure on the lip gasket after the nut has been tightened allowing an ideal compression of the gasket on the pipe. The thrust ring grips the body so that it cannot be lost in cases where disassembling of the fitting is required.
    2.1 For fittings Ø 75-90-110: The polypropylene thrust ring defines, while tightening the nut, the compression of the spring gasket (see pt. 5′).
  3. The floating split ring, in polyacetal, allows perfect resistance to possible pull-out forces without having a negative impact on the tightness of the fitting.
  4. The nut in light blue polypropylene offers an outstanding resistance to impact. The nut is perfectly resistant to UV rays, too.
  5. The only fitting with “prelubricated double lip gasket” in NBR patended by Georg Fischer allowing to overcome: ovalizedscratched-undersized pipes. Thanks to the active sealing system, the double lip gasket guarentees a perfect adherence to the pipe increasing the contact surface. The double lip gasket grants high resistance in case of vacuum and/or suction, too.
    5.1 For fittings Ø 75-90-110: A fitting with spring gasket that simplifies and speeds up the insertion of the pipe assuring a perfect and constant seal and resistance to the internal pressure even in case of ovalized/scratched-undersized pipes, thanks to the particular shape of the gasket that covers a wide surface of the pipe. The lip-shape of the inferior part of the gasket allows its optimal placing into the seat of the body and the constant keeping of its position during the time granting a high resistance also in case of vacuum and/or suction.

Assembly Instructions

Ø 16 – 63

  1. Please check all components (seal, thrust ring, split ring). Cut the pipe square and deburr it. Grease the seal, in case it is dry. Partially unscrew the nut
  2. Mark the insert depth on the pipe. Push the fitting on the pipe through the split ring until the first stop, meaning you have reached the seal.
  3. Push the pipe through the seal until you reach the pipe stop of the fitting.
  4. Tighten the nut as tightly as possible. Tightening with Alprene Plus dedicated wrench recommended up to size 40.

x

Ø 75 -110

  1. Please check all components (gasket, thrust ring, split ring). Cut the pipe square and deburr it. No chamfering. Partially unscrew the nut.
  2. Push the fitting on the pipe until you have reached the pipe stop.
  3. Tighten the nut as tightly as possible with an Alprene Plus wrench, or a special wrench for fittings.
