Legris 0121 17 17 Hex Plug 3/8 in Mbspt Brass

Product Description

The LEGRIS 0121 17 17 is a straight hex plug fitting designed to seal off 3/8 inch male BSPT threaded ports in industrial piping systems. Machined from brass, this plug handles a maximum working pressure of 1000 psi and a maximum working temperature of 302 degrees F, making it suitable for a wide range of fluid and pneumatic service applications. Its hex-head design allows standard wrench engagement for secure installation. Licensed trade professionals and industrial maintenance technicians rely on this type of fitting to terminate unused ports cleanly and reliably.

This hex plug is suited for use in industrial fluid power, pneumatic, and compressed air systems where BSPT threaded connections are specified. Common installation scenarios include sealing unused manifold ports, valve bodies, and distribution blocks in both light and heavy industrial environments. The brass construction provides good corrosion resistance in non-corrosive media applications. It ships individually and is well-suited to both single-unit service repairs and multi-unit panel or manifold builds.

• Operating temperature range of -40 degrees F to 302 degrees F
• Straight hex plug profile for standard wrench installation
• Compact and lightweight at approximately 0.055 pounds

Compatibility

Designed as an OEM-style replacement or maintenance fitting for industrial piping and fluid power systems using MBSPT-threaded ports and components.

Installation Notes

Installation is performed by qualified plumbers, pipefitters, or industrial maintenance technicians. Shut down system pressure and bleed all residual pressure from the line before removing or installing any threaded plug fitting. Use an appropriate thread sealant or PTFE tape on the male BSPT threads per the system manufacturer and applicable codes. Engage threads carefully by hand before applying a wrench to avoid cross-threading the port.
