Ensure the pipe is free from all score marks and deformities in the area of the
insertion depth (Fig. 7) and cut the pipe square removing all burrs and sharp
edges to prevent damage to the sealing 'O'-ring.
2. Prior to inserting pipe into fitting mark the insertion depth on the wall of the
pipe with a soft pencil at a distance of 33 mm from the end to be inserted.
