Midland Industries 030616 Jic Bulkhead Locknut 1 in Steel

Product Description

The MIDLAND INDUSTRIES 030616 is a steel JIC bulkhead locknut designed to secure bulkhead fittings in hydraulic system panels, bulkheads, and enclosures. With a 1-inch nominal size and 1-5/16-12 thread specification, this locknut provides a firm mechanical hold on JIC-style bulkhead fittings installed through a panel or wall. It is part of the 0306 Series and is used across hydraulic plumbing applications where a threaded locknut is needed to retain a fitting from the opposite side of a mounting surface. Hydraulic technicians and fluid power mechanics install this hardware as part of line assembly and panel fabrication work.

The 030616 is suited for steel JIC adapter installations in industrial and mobile hydraulic systems. It is a standard component used wherever a bulkhead fitting must be anchored securely to a panel or enclosure wall. The 1-inch nominal size fits common hydraulic line configurations, and the 1-5/16-12 thread pitch matches JIC bulkhead fitting thread standards. Applications include hydraulic power units, manifold enclosures, and mobile equipment hydraulic panels.

Compatibility

Designed as an OEM-style replacement or service component for steel JIC bulkhead fitting assemblies in hydraulic systems requiring a 1-inch nominal, 1-5/16-12 threaded locknut.

Installation Notes

Installation is performed by hydraulic technicians or fluid power mechanics during panel fabrication or fitting replacement. De-pressurize and bleed down the hydraulic system fully before removing or installing any bulkhead hardware. Thread the locknut onto the bulkhead fitting from the reverse side of the mounting panel and tighten using an appropriate open-end or adjustable wrench. Follow applicable hydraulic system safety standards and equipment manufacturer guidelines for fitting torque and assembly procedures.
