Question by: Dwight H on Dec 27, 2025, 6:42 PM
Got a hand pump setup I been using for a while now, wondering if this coupler'll hold up pressure-wise for that kind of work?
Answer by: Customer Support on Dec 29, 2025, 6:37 PM
Hand pump setups are pretty much the sweet spot for this coupler. It handles up to 10,000 psi, which covers the operating range of most hand pump systems without any trouble. The AR-400 is rated for medium-duty work, so regular hand pump use is exactly what it was built around. Comes with a female steel dust cap too, which helps keep the port clean when it's not hooked up.

Need a quick-connect for a hand pump setup, is this the right coupler or is it more for heavy equipment
Answer by: Customer Support on May 20, 2026, 3:01 PM
For medium-duty hydraulic work, the Regular Spee-D-Coupler female half is a solid match, especially on hand pump applications. It is intended for flow rates up to 462 in3/min (7.6 liters) per minute and it is rated for 10,000 psi (700 bar).
