Watts (TK-PRO-20.VV) Tank Ball Valve Kit for TK-PRO-20U 3-4" NPT - 3-8" Tube
Watts TK-PRO-20.VV Tank Ball Valve Kit
3/4" NPT to 3/8" tube compression adapter with integrated ball valve for pressurized RO storage tanks
The Watts TK-PRO-20.VV is a threaded adapter kit that converts the 3/4" Female NPT port on standard reverse osmosis storage tanks to a 3/8" compression tube connection, with an integrated ball valve for isolation and maintenance. Designed specifically for use with the Watts TK-PRO-20U and similar pressurized water storage tanks.

What Makes This Kit Essential
Thread Conversion
Adapts standard 3/4" NPT tank ports to 3/8" compression tubing used in most residential and light commercial RO systems
Integrated Shutoff
Ball valve allows you to isolate the storage tank for filter changes, system maintenance, or tank replacement without draining lines
Leak-Free Seal
Compression fitting creates a secure, tool-tightened seal on 3/8" OD tubing without requiring soldering or glue
Universal Fit
Works with Watts TK-PRO-20U and most standard pressurized RO storage tanks from 0.5 to 20 gallons with 3/4" NPT ports
System Integration
This valve kit is designed for use with the Watts TK-PRO-20U and similar reverse osmosis pressurized storage tanks featuring 3/4" Female NPT threaded ports. It's compatible with 0.5 gallon, 14 gallon, and 20 gallon tank sizes commonly used in residential under-sink RO systems and light commercial applications. The 3/8" compression outlet connects directly to standard RO system tubing without additional fittings or adapters.
Watts has been engineering reliable water treatment components for decades, and this tank valve kit reflects that same focus on durability and proper thread tolerances.
