    3/8″ Female NPT Straight Through Brass Coupler

    Part #: MM-86-036

    3/8″ Female Straight Through Brass Coupler designed for uninterrupted high-pressure fluid or gas transfer. Constructed with a solid yellow brass body and valve, this coupler uses a Buna-N seal, stainless steel spring, and 8 hardened steel locking balls for secure retention and reliable performance. Its straight-through design means there is no automatic shut-off on disconnect, ensuring constant flow. Suitable for use in water, steam, compressed air, vacuum, hydraulic oil, and gas systems. Built for high-pressure applications up to 4000 PSI and ideal for pressure washers, carpet cleaners, and steam equipment.
