John Guest Locking Clip Suit 12mm Fittings Red 20PK gives your 12mm push fittings a solid mechanical lock so they stay put on rough tracks and corrugated roads. Each clip wraps around a standard 12mm fitting collar and pipe, so you can tackle long touring days without constantly checking joins. The bright red colour makes it simple to spot which lines are locked when you crawl into a front boot or underseat hatch. This 20 pack covers a full van plumbing layout with spare clips on hand for later jobs, making it a smart buy for anyone who tweaks their own setup. Each clip sits around 4cm x 4cm x 2cm and adds roughly 20 grams, so it will not load up your kit. A 1 year warranty backs the gear for repeated clip on and clip off use in Aussie heat and dust.

Q: Will these clips work with any 12mm pipe system?

These clips suit 12mm John Guest style push fittings used with 12mm pipe. They are shaped to lock over the fitting collar and pipe size listed. For best results match them with genuine or equivalent 12mm push-fit fittings. Mixing sizes or different fitting types can reduce how well the clip grabs the collar.

Q: How many fittings can I lock with one pack?

One pack contains 20 locking clips, so you can lock up to 20 individual 12mm fittings. That usually covers key joins around pumps, tanks and appliances plus a few spares. Planning out your plumbing run before installation helps you decide where each clip gives the most value. Keeping a couple in the toolbox is handy for on-road repairs.

Q: Can I remove and reuse the locking clips?

The clips are push-on pieces that can be removed if you need to alter the plumbing. You simply lever the clip off the fitting to release the collar. Take care not to twist them past their natural opening so you do not stress the plastic. Reusing clips that still hold their shape is generally fine for similar 12mm fittings.

Q: What maintenance do these clips need over time?

The clips themselves do not need regular maintenance beyond a quick visual check. Looking for cracks, distortion or UV damage when you service your plumbing is usually enough. Any damaged or loose clip should be swapped for a fresh one from the pack. Keeping them out of direct sunlight when stored will help the plastic last longer.
