Making a push fit joint

Options
Download Details
  Step 1

Cut the PE-X pipe to length using the Marley pipe cutter or similar plastic pipe cutter. Slight pressure as if to twist the cutter around the pipe will aid cutting.

Check that the pipe end is clean, cut square and free of burrs and without surface damage.

Notes

O-rings are pre-lubricated, but additional lubricant may be used on pipe end when working within restricted arm room to ease jointing.

Soldering Flux

The transfer of flux traces by handling with contaminated hands is not detrimental to Equator pipework. The spillage or flow of flux onto equator products during the soldering of adjacent copper pipework must be avoided.
  Step 2   Push a pipe support sleeve fully into the pipe end.  

When making push-fit joints onto spigot ends of PE-X fittings, a pipe support sleeve is not required. This applies to stop end for fittings, spigot elbow, and spigot tee.

DO NOT USE OTHER BRANDS OF PIPE SUPPORT SLEEVES WITH EQUATOR PIPE
  Step 3   Using a suitable pencil or biro pen, mark the insertion depth on the pipe end. Moulded fittings have an insertion depth line on the fitting bodies. Otherwise, measure the insertion depth in accordance with dimension Table 7.

  Step 4   Push the pipe into the socket until the insertion mark on the pipe meets the edge of the socket.    
  Step 5   To confirm that the joint is secure, tug backwards on the joint.    
 

Demounting a push fit joint

 
  Step 1   Using the plastic demounting tool, place tool around pipe with the lugs facing the joint.   Fittings can be reused providing there is no damage evident to the O-ring. If an Equator fitting has been removed from a system which has been in operation, it is advisable to flush out the joint with clean water, and allow to dry off before reusing. When reusing an Equator fitting, apply a smear of silicone lubricant around the pipe end.
  Step 2   Locate the four lugs to align with the slots on the face of the fitting and push the tool towards the fitting, using equal pressure around the tool.   A de-mounted pipe end will show 'drag' marks where the pipe has been pulled back through the grip ring. These marks will vary according to the degree of operative care during de-mounting. Wherever possible, it is recommended that the original insert depth is trimmed off the pipe end. A pipe end may be reused providing it is not damaged.
  Step 3   Holding the pipe firmly in one hand, grip the end of the de-mounting tool with the other hand and gently pull the pipe to release the joint.   In order to ensure that an Equator fitting is de-mountable when installed, there must be enough clear space in front of the joint face to allow the demounting tool to be used. The minimum dimension between two opposing Equator joints or between the face of an Equator joint and an obstruction is as shown in fig 3.
