300 lb. Black Pipe Fittings
When 150 lb fittings are the weak link, step up to Class 300 black pipe fittings. You get precision threads and chamfered starts for fast make-up and fewer cross-threads on rugged service lines. Use 45° and 90° elbows or street elbows for tight turns, tees for branches, couplings and reducers for size changes, nipples for runs, caps for dead ends and unions for quick take-apart. We keep Kimball Midwest stock ready.
