Dixon Valve Coupling 1720202C Brass Hex Plug 1/8 in

Product Description

The DIXON VALVE COUPLING 1720202C is a brass hex plug designed to seal off pipe and fitting ends in pressurized fluid and gas systems. It features a 1/8 inch male thread with an MNPSM x MNPTF connection type and is rated to a maximum working pressure of 1,000 psi. The hex head allows for standard wrench installation and removal. This type of plug is a standard component in plumbing, hydraulic, and pneumatic systems where a threaded port must be capped securely. Brass construction provides corrosion resistance suitable for water, air, and many common fluid services. At 0.1 pounds, it is compact and lightweight for easy handling and stocking.

This hex plug is used in residential and commercial plumbing, HVAC, and light industrial piping applications where a 1/8 inch male-threaded port requires a leak-tight seal. Typical install scenarios include capping unused ports on manifolds, valves, pumps, and fittings. The MNPSM x MNPTF thread classification makes it appropriate for use in both straight mechanical seal and tapered thread configurations. Licensed plumbers and HVAC technicians commonly stock this fitting for service and new-construction work.

Key Features

• 1/8 inch male thread for standard pipe fitting applications
• MNPSM x MNPTF connection type for compatible straight and tapered thread ports
• 1,000 psi maximum working pressure rating

Compatibility

Designed as an OEM-style replacement or service fitting for any application requiring a 1/8 inch male-threaded hex plug with an MNPSM x MNPTF connection rated to 1,000 psi.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or pipefitters. Shut off and depressurize the system completely before removing or installing any threaded plug. Apply an appropriate thread sealant or PTFE tape to the male threads per the system requirements and applicable plumbing or mechanical codes. Do not overtighten brass fittings, as the material is softer than steel and susceptible to thread damage.
