This John Guest 12mm locking clip kit keeps your push-fit joints in place on caravan or RV plumbing runs that see plenty of vibration. Each clip suits standard John Guest 12mm fittings on cold water lines and manifolds. The bright red gear stands out under benches and in tunnel boots so you can spot which joins are locked before you hit the corrugations again. Each clip comes in a compact 4cm by 4cm by 2cm body so it fits around tight plumbing clusters without crowding valves or elbows. Single clips weigh 20 grams so ten pieces add barely any weight to your toolbox. The pack includes ten 12mm clips so you can cover key joints around pumps and tanks. A 1 year warranty backs the construction for normal touring use in Australian conditions.

Q: Can I reuse these John Guest 12mm locking clips after disconnecting a fitting?

Yes, the clips can be removed and reused if they are not damaged. Slide the clip off the collar before disconnecting the 12mm fitting, then store it with your plumbing gear. Inspect for cracks or deformation before putting it back on a new joint. Replace any clip that no longer grips the collar evenly.

Q: Are these clips suitable for hot water lines as well as cold water lines?

The clips are specified as locking clips for John Guest 12mm fittings, which are commonly used on both hot and cold circuits. Always match them with fittings and pipe that are rated for the temperature in your system. Check your existing 12mm plumbing for John Guest markings before use. Avoid mixing with fittings from other systems that may have different tolerances.

Q: How many 12mm fittings can I secure with one 10-pack?

One 10-pack will secure ten individual 12mm fittings. Each fitting requires a single locking clip around the push-fit collar. Count up the number of critical joins near pumps, tanks, and appliances before ordering. Keep one or two spare clips in your toolkit for future changes.

Q: Do these locking clips add noticeable bulk around the fitting?

The clips measure roughly 4cm by 4cm by 2cm, so they add only a small ring around each 12mm fitting. Most under-sink and under-bed plumbing layouts have enough clearance for this profile. Always check tight spots near walls or cabinetry when planning your plumbing runs. If access is tight, fit the clips before final mounting of nearby panels.
