The Macnaught KY+ Safety Grease Coupler features a patent-pending smart-release mechanism for ease of use and speed. Macnaught’s floating jaw operation creates a powerful, leak-free connection while improving safety, the company says. The KY+ click-on and -off connection enables one-handed engagement and disengagement of the grease fitting. The coupler has a patent-pending internal, hydraulic pressure-relief system to reduce the risk of high-pressure grease discharge and to provide safe disconnection of the coupler at up to 10,000 psi. Its compact design fits into tight spaces, providing greater accessibility. The KY+ Safety Grease Coupler is suitable for automotive, truck and bus, marine, construction, mining, aviation and agriculture applications, as well as for plant equipment.
