Couplings Female thread Series 217 High-Flow, 72 MPa NPT 1/4"
Series 217 High-Flow, 72 MPa
Series 217 couplings and nipples offers a superior flow performance in relation to working pressure. The product has a flat-face design that keeps air inclusion and spillage down to a minimum, protecting both the hydraulic system and the environment from contamination. The flat-face feature also enables one-handed operation and easy maintenance. To prevent unintentional connection and disconnection during operation, a safety lock is standard on all couplings. The CEJN Series 217 ultra high-pressure hydraulic quick disconnect is particularly suitable for high flow hydraulic systems.
