COMPATIBILITY & APPLICATIONS

Where This Valve Fits

The VV-TKB38 is designed for reverse osmosis systems, water filters, ice makers, and refrigerator water lines where you need to connect 3/8" plastic or nylon tubing to a 1/4" threaded port. Common applications include tank shutoff valves, feed water control, and permeate line isolation. The quarter-turn handle provides instant on/off control, making it ideal for maintenance shutoffs or emergency isolation. Compatible with standard compression fittings and works with polyethylene, nylon, and LLDPE tubing rated for potable water.

💧 Pro Tip: When installing compression fittings on the 3/8" side, hand-tighten the nut until snug, then add one additional quarter turn with a wrench. Over-tightening can crush the ferrule and cause leaks over time.
