Push to Connect 1/8-NPT by 1/4-OD tubing

This push-to-connect straight union fitting bridges 1/4-inch OD tubing to a 1/8-inch NPT port with reliable, leak-free performance. Constructed from nickel-plated copper, it handles air, water, and oil applications across a working pressure range of 0-145 PSI, giving you confidence in everything from vacuum systems to pressurized lines. The durable design operates smoothly from 32°F to 140°F, making it equally at home in winter garage sessions or summer track days.

The straightforward push-to-connect design means no tools, no fittings to wrench on—just insert your tubing and you're done. Whether you're plumbing a custom air intake, routing coolant lines in a modified cooling system, or setting up pneumatic suspension components, this adapter makes clean, professional connections without the headache. Built tough to handle negative pressure down to -29.5 inches of mercury, it won't let you down when precision tubing work matters.

If you're assembling custom performance systems and need bulletproof connections that work first time, every time, this fitting belongs in your build.
