Weld-In Half Coupling – Stainless Steel – 1/4 in. or 3/8 in. NPT

Stainless steel weld-in half coupling designed for adding threaded ports to fuel tanks, oil tanks, or other fabricated reservoirs. These couplings provide a clean, permanent solution for installing additional fittings where a threaded connection is required.

Commonly used to add vents, pickup tubes, returns, or drain fittings, each coupling features female NPT threads and a compact half-coupling design that welds flush into the tank surface. Stainless steel construction offers excellent corrosion resistance and long-term durability.
