A 3 inch polypropylene bulkhead fitting for fast fills and drains
Part number 62299 is Norwesco's 3 inch bulkhead fitting in polypropylene, the largest common outlet size on their tank range. It passes through the tank wall, seals with a gasket on the inside, and gives you a 3 inch threaded connection on the outside for a valve, camlock or pipe. Three inches is the size to choose when a tank has to empty or fill quickly: a nurse tank feeding a sprayer, a transfer tank on a trailer, a storage tank that drains by gravity into a pump. The body is about 4 inches across and the fitting ships in an 8 inch carton by UPS.

What to check before you buy
- The size. 3 inch. Everything downstream, valve, hose and pump inlet, should be 3 inch too, or you lose the flow you paid for at the first reducer.
- The wall. A 3 inch bulkhead needs a larger flat area on the tank wall than a 1.5 or 2 inch one, at least the width of its flange. Check the fitting drawing against the tank drawing before you cut a bigger hole in a tank that came with a smaller outlet.
- The liquid. Polypropylene suits water, fertilizers and many common chemicals. For anything aggressive, check the liquid against the material first and ask us if it is not on the list.
- The weight hanging on it. A 3 inch valve and a length of 3 inch hose are heavy. Support them on their own so the fitting carries liquid, not hardware.
Norwesco's drawing for this fitting is linked on this page under Technical Drawing and shows the flange and the hole size.
Installing it
Dry-fit first and turn the body so the outside thread points along the pipe run, then tighten the nut by hand plus a quarter turn with a wrench. On a big fitting it is tempting to keep going; do not, because a crushed gasket is the usual cause of a slow weep that appears a week later. Keep a spare gasket with the tank paperwork.
Shipping
The fitting travels by UPS from the nearest of Norwesco's plants. The listed price is before freight; the freight cost estimator gives the cost to your ZIP. If it is going on a new tank, order both together so the tank arrives ready to plumb.
