In addition to being lightweight, these aluminum fittings offer good corrosion resistance. Use them in low-pressure flow applications. To prevent cracking, do not tighten more than a 1/4-turn past hand tight.
Threaded Fitting Connection — Threaded female x butt weld straight adapters are also known as half couplings.
Note: This is McMaster's suggested substitute for 44705K322 (discontinued). 44705K922 is 31/32" long vs 1" on K322, and does NOT meet MIL-DTL-52618.
