3/8in Vac Fitting Push To Connect 1/8in NPT

The 3/8in Vac Fitting Push To Connect 1/8in NPT is a professional-grade air line adapter designed for pneumatic systems requiring secure, leak-free connections. Built by REDHORSE PERFORMANCE under model 4716-02-06-5, this fitting bridges 3/8-inch female quick disconnect ports to 1/8-inch NPT male threads, making it essential for vacuum, air brake, and compressed air applications across automotive, industrial, and motorsports environments. The push-to-connect design eliminates the need for tools or wrenches, enabling fast setup and field adjustments without downtime.

Manufactured from steel and finished with nickel plating, this adapter delivers corrosion resistance and durability in high-vibration and moisture-prone settings. The nickel-plated steel construction withstands pressure cycling and thermal fluctuations while maintaining seal integrity, critical for vacuum-operated systems where even minor leaks compromise performance. The 1/8-inch NPT male end ensures compatibility with standard industrial pneumatic components, while the 3/8-inch female quick disconnect receiver accepts push-lock couplers that prevent accidental disconnection and minimize air loss during coupling and uncoupling.

Mechanics, technicians, and fabricators benefit most from this fitting when upgrading or repairing brake booster lines, vacuum distribution networks, and auxiliary pneumatic systems on vehicles and machinery. Installation is straightforward: simply screw the NPT male end into any threaded port accepting 1/8-inch NPT, then push the quick-disconnect coupler onto the 3/8-inch female receiver until it locks. Its compact 2.8 x 1.1 x 3.8-inch profile and lightweight 0.07-pound construction make it ideal for tight engine bays and custom fabrication projects where space is at a premium.
