Constructed from premium Aluminum 6061‑T6, these full couplings deliver exceptional strength and superior resistance to rust and corrosion compared with standard steel fittings. Both ends feature female 3/8″ NPT threads (FxF) machined to exact industry tolerances, providing a tight, leak‑proof seal for compressed air, water, oil and other non‑flammable fluids.

With a pressure rating of 150 PSI, the couplings are ideal for industrial, agricultural, automotive and DIY projects where reliability is essential. Installation is straightforward—apply Teflon tape or pipe dope to the threads and tighten with a standard wrench. Each package includes two inspected couplings ready for immediate use.
