Overview – PLUG-PIPE SOC DRIVE 185-2188
185-2188 is the socket drive pipe plug used on CUMMINS engines and hydraulic circuits to seal threaded ports in blocks, manifolds and housings. We can supply this pipe plug as well as related CUMMINS plugs and fittings, in stock or available on order – welcome to enquire by part number.
Parts Characteristics
The plug is machined from steel with a tapered pipe thread and a socket drive head, matched to the original CUMMINS port specification. The thread form and coating provide a leak-free seal in oil, coolant and hydraulic ports. The socket drive allows installation with a hex key or socket without damaging the head. As an OEM-spec plug, it screws into the original port and seats without additional sealing compound when the port is clean.
Applicable Models & Applications
This pipe plug is used on CUMMINS engines and hydraulic systems to seal ports in cylinder blocks, oil pans, filter housings, manifolds and valve bodies. Confirm the thread size, pitch and port depth against the plug removed from your machine before ordering.
Maintenance & Replacement
Check plugs during oil and coolant service for looseness, thread damage and signs of leakage around the head. A leaking plug should be removed, the port cleaned and the thread inspected before fitting a new plug. When installing, clean the threads, fit the plug hand-tight to engage the taper, then tighten to the original torque. Do not over-tighten, which can crack the port boss.

Value & Service
An undersized or wrong-thread plug can strip the port, so we verify 185-2188 against the original CUMMINS thread specification before dispatch.
