The HPX non-spill quick couplings are ideal for heavy duty, high pressure hydraulic applications – when a secure connection is most crucial. A screw locking mechanism with outer ratcheting collar for added safety guarantees extremely robust connections, even if subjected to intense pulsating or vibrating cycles. Optional colored alloy caps allow instant visual identification of circuits. For easier handling, the plugs can be fitted with a hand wheel.
