NIFTBS050 10-12mm (3/8"-1/2") "Nut In" Straight Bulkhead Fitting

Nut in fitting 10/12mm Straight Bulkhead Black Plastic Water Tank Fitting

Nut In fitting 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 pass through into the tank rather than having a completely open hole in the Tank.
