Midland Industries 9644-C-12 Bspp Swivel Cap 3/4 in Steel

Product Description

The MIDLAND INDUSTRIES 9644-C-12 is a steel BSPP swivel cap designed to seal and protect 3/4-inch female BSPP swivel ports in hydraulic systems. The cap threads onto a 3/4-14 BSPP port to block contamination, prevent fluid leaks during storage, transport, or maintenance, and maintain system integrity when a line is disconnected. Built from steel, it delivers the durability required for hydraulic plumbing environments. This fitting is a standard component in hydraulic adapter assemblies and is installed by hydraulic technicians, maintenance mechanics, and fluid power specialists working on industrial and mobile hydraulic circuits.

The 9644-C-12 is suited for hydraulic systems that use BSPP (British Standard Pipe Parallel) threaded ports, common in industrial machinery, mobile equipment, and fluid power circuits. It is used wherever a 3/4-inch female BSPP swivel port needs to be capped off during system service, component replacement, or equipment downtime. The swivel design allows for easy hand-tightening and removal without requiring the mating port to be rotated.

Installation Notes

Installation and removal should be performed by a qualified hydraulic technician or mechanic. Before capping any port, depressurize the hydraulic system completely and relieve all residual pressure per standard safe-work procedures. Hand-tighten the swivel cap to seat it properly, then use an appropriate wrench for final torque, following the system manufacturer's fitting specifications. Inspect the sealing surfaces for damage or contamination before installation to ensure a leak-free connection.
