John Guest
John Guest makes push-fit fittings and pipe for compressed air lines. Air supply system kits come in 2, 3 and 5 drop versions, with aluminium or rigid nylon air pipe in 15, 22 and 28mm, tees, elbows, water trap tees and wall boxes. SharkBite air fittings use anodised aluminium pipe. Smaller push-fit couplings and adaptors suit 6, 8, 10 and 12mm polyethylene tubing.
