NIFTBA050 10-12mm (3/8"-1/2") "Nut In" Bulkhead Elbow 10-12mm Hose Barbs

10/12mm Elbow Bulkhead Red Plastic Water Tank Fitting

for caravans, motorhomes, horseboxes, sporthomes & garden water butts "NutIn" comes with relevent nut and washer, although with a bulkhead it works slightly different to a standard "nut in" fitting  whereas a conventional fitting would just have a nut this has a second hose connector so it can be used as a hose pas though into the tank rather than having a completely open hole in the tank.
