PVC-U IMPERIAL FITTINGS PLAIN/THREADED:
PVC-U (Unplasticised polyvinyl chloride) is one of the most popular thermoplastic
materials used for pressure pipework installations. Light in weight PVC-U has excellent resistance "to chemicals and abrasion, is tasteless and odourless making it ideal for use with" potable water systems and most food products as its extremely smooth bore gives excellent flow characteristics without sediment or deposit.
INSTALLING THREADED FITTINGS:
1. Ensure all threads are clean.
2. Apply PTFE tape to the male thread for 11
⁄2 turns in a clockwise direction.
3. Screw the female threaded fitting by hand onto the male thread.
4. It should be possible to screw the fitting on by hand for 2⁄3 of the thread length.
5. After tightening by hand add an extra 1⁄2 turn with a suitable tool ie strap wrench
PRECAUTIONS:
Use PTFE tape only. Do not use thread seal paste or any other jointing compound. Do not force tightening of the joint
under any circumstances. For connecting plastic pipework systems to metal pipework systems composite unions and/or flanges must be used.
