FAP water filler cap with New System cylinder and 2 keys, black - motorhome and caravan
- Replacement black FAP cap for a water filler in a motorhome or caravan. It has a two-spoke grip, a New System cylinder and two keys included, so you can lock your tank.
This FAP cap is a spare part for the fresh water filler of a motorhome or caravan. It is round with a two-spoke grip that you can hold firmly even with gloves on. Inside there is a New System cylinder and a pair of keys is included, so you can lock the tank and nobody can pour anything into it. The cap is useful when the old one has cracked, got lost or you no longer have its keys. In black it matches fillers in the same colour, and the cylinder belongs to the New System range, for which you can buy spare keys and cylinders.

What to keep in mind
Before you order, compare your old cap with the photo and measure its diameter. The cap has to fit the filler you put it on. The cylinder belongs to the New System range, so the shop has a spare key pair, a complete cylinder with keys and a cylinder extraction key. Keep the keys in a fixed place in the vehicle and the spare key preferably outside it.
Care
- Wipe the seal with a damp cloth when sand settles on it.
- Do not use solvents.
- If the lock turns stiffly, clean the dust out before using force.
