Your fresh-water filler cap's cracked, the lock's gone, or you're fitting a new tank and need a proper sealed inlet. This 25 mm lockable filler and cap kit slots into the standard caravan and RV fresh-tank opening. The larger 25 mm tube handles your hose flow without dripping; the smaller 8 mm tube suits inline fittings. Lockable cap means no one's topping up your tank at the campsite. Black finish blends with most tank housings. RTM stocks a range to suit the major caravan and RV models, so grab the right diameter for your setup and you're sealed up before the next fill
