About John Guest Fittings & Hose

John Guest hose and fittings are the push-fit system caravanners, plumbers and beverage techs use when they want a secure joint without tools. Cut the tube square, push in an insert, push the tube into the fitting and the collet grips it. Hose Suppliers Australia stocks the acetal fittings, the tube and the small parts that go with them in both 12 mm and 15 mm.

John Guest hose and fittings we stock

  • Tube by the metre: John Guest blue, red and black tube, cut to length, in 12 mm and 15 mm so you can colour code cold, hot and general lines.
  • 12 mm fittings: equal straight, elbow and tee connectors, bulkhead connectors, 3/8" and 1/2" male and female BSP adaptors including a brass adaptor, shut off valves, tube inserts, locking clips, pipe saddles and plugs.
  • 15 mm fittings: joiners, elbows, tees and end caps, 1/2" male and female BSP adaptors, shut off valves, tube inserts, locking collars and pipe saddles.
  • Related ranges: caravan plumbing fittings and the wider poly, nylon and John Guest category.

Choosing the right John Guest fittings

  • Size: the number is the tube outside diameter, so a 12 mm fitting only takes 12 mm tube. Check before you order a boxful.
  • Thread: adaptors are BSP, in male and female, so confirm which one your tap, pump or filter housing needs.
  • Inserts and clips: use an insert in every flexible tube end, and a locking clip or collar on lines that get knocked.
  • Compatibility: the fittings suit John Guest tube and approved polyethylene tube of the same outside diameter.
  • Isolation: fit a shut off valve at the tank or pump so you can work on a line without draining the system.

John Guest supply can run short on individual lines from time to time; if anything on your order is affected our staff will contact you directly rather than hold the whole order. Call the Brisbane team on (07) 3890 3359 or contact us for a parts list, see the poly fittings range for barbed alternatives, and apply for a trade account if you fit out vans or filtration systems.
