Straight Through Couplers
Straight Through Couplers
Straight Through Air Couplers provide unrestricted flow of liquids or gases, making them ideal for pressure washers and high-pressure cleaning applications. Constructed entirely of brass—including the socket body, sleeve, and nipples—they offer excellent corrosion resistance and durability. With no automatic shut-off, flow must be stopped before disconnecting to ensure safety. Suitable for MRO tasks requiring maximum flow rates. Always depressurize the system before disconnecting to prevent accidents.
