Infinity 1/4″ Industrial Plugs (M-Style)
The Strong Link in Your Air Chain
Complete your connection setup with Infinity 1/4″ Industrial Plugs. While the coupler provides the mechanism, the plug (or nipple) takes the abuse. It is the component attached to your impact wrench, sander, or blow gun—dragged across concrete floors, dropped, and subjected to constant vibration.
Infinity plugs are engineered to withstand this harsh environment. Manufactured to precise Industrial Interchange (M-Style) standards, they ensure a perfect, wobble-free fit with Infinity Industrial Sockets, preventing the premature wear that leads to hissing leaks and pressure loss.
Available Configurations
- Male NPT Thread: Screws directly into the inlet of your air tool or female manifold port.
- Female NPT Thread: Screws onto the end of a male-threaded air hose or rigid pipe nipple.
Key Features & Benefits
- Case-Hardened Durability: Unlike cheap, soft metal plugs that develop grooves and scratches (which then cut the coupler’s internal O-ring), Infinity plugs are case-hardened. This heat treatment creates a tough outer shell that resists wear from the coupler’s locking balls, significantly extending the life of both the plug and the socket.
- Industrial Standard (M-Style): Built to the MIL-C-4109 / ISO 6150 B specification. These plugs are universally compatible with any brand of 1/4″ Industrial (M-Style) coupler, making them the versatile choice for any shop.
- High-Flow Geometry: Designed with an optimized internal bore to minimize airflow restriction, ensuring your tools receive the maximum possible pressure for peak performance.
- Corrosion Resistant: Plated to resist rust and oxidation, ensuring a clean connection that won’t seize into your tool inlet or contaminate your air supply.

Why Quality Plugs Matter
A scratched or dented plug is the #1 cause of coupler failure. When a damaged plug is inserted, it slices the internal seal of the coupler. Investing in high-quality, hardened Infinity plugs protects your more expensive couplers and keeps your system leak-free.
Stop replacing couplers. Start using better plugs. Stock up on Infinity 1/4″ Industrial Plugs today.
