Coupling (screwing) and uncoupling (unscrewing) of the two halves is safe and very easy. After the connection is complete, all internal components have minimal play or clearance, which significantly reduces the risk of material fatigue. Another advantage is that the risk of permanent indentation, so-called "brinelling", on the surface of the male tip is eliminated, which can occur with push-to-connect couplings in similar extreme applications. The proven design is suitable for use in oil and gas industry as well as mobile equipment and heavy duty transportation, especially where high pressures, high flow and pulse pressure are present. The design used heavy-duty ACME thread for durable connection strength and a heavy-duty poppet valve design that prevents seal washout under operating parameters. Series HV are used on Hydraulic tippers and available in nominal sizes 19, 25, 31, 38, 51 (3/4" - 2"). § Poppet Valve § Zinc-Plating and Thick-Film-Passivation (Chrome III) § Can be connect under pressure up to 100 bar (1450 PSI) Applications Top Features Vibration resistant Designed for secure connection Construction Machinery Oil and gas industry Connect Under pressure
