1 1/4" Bulkhead
$19.99
1 1/4" Bulkhead. A bulkhead fitting passes plumbing through a tank wall with a sealed, mechanically secure connection on both sides.
Match the material to the service. Stainless resists chemicals best, brass suits general water service, plated steel is economical for clean water, and poly or PVC belongs on chemical and low-pressure lines.
Bulkhead fittings need their gasket seated correctly and the nut tightened evenly — overtightening cracks poly tank walls, and undertightening leaks.
Grime Task Force stocks fittings across materials and sizes because a rig is only as reliable as its plumbing, and a single wrong or failing fitting can shut down a job. Keeping common sizes on the truck turns most plumbing failures into a short delay instead of a lost day.
