Midland Industries 5406C2 Steel Pipe Cap 1/8 in Female Nptf

Product Description

The MIDLAND INDUSTRIES 5406C2 is a steel pipe cap designed to seal female NPTF threaded ports in hydraulic and high-pressure fluid systems. Rated to 5000 psi maximum operating pressure and 375 degrees F, this cap provides a reliable dead-end termination on unused or inactive ports. The 1/8-27 thread size fits standard 1/8 in female NPTF connections. Constructed from steel, the 5406C2 is built to hold up in demanding hydraulic circuit applications where pressure containment and leak-free sealing are critical. Licensed plumbers, hydraulic technicians, and industrial pipefitters typically install this type of fitting during system assembly or when blanking off ports during service.

The 5406C2 pipe cap is suited for use in hydraulic systems, high-pressure fluid lines, and steel pipe adapter assemblies where a durable, pressure-rated port seal is needed. The female NPTF connection provides a dry-seal thread engagement that reduces the risk of fluid bypass without relying solely on thread sealant. This cap is commonly used in industrial, mobile hydraulic, and fluid power applications requiring a compact, low-profile port closure.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or hydraulic technicians. Always depressurize and bleed down the hydraulic system fully before removing or installing any pipe cap or fitting. Apply thread sealant or PTFE tape as appropriate for the system fluid and pressure rating, following the system manufacturer and applicable code requirements. Inspect threads for damage before installation to ensure a proper seal.
