Watts AquaLock - Large Diameter Reducing Stackable Valve
Technical Details
| Manufacturer | Watts Water Technologies |
| Product Line | AquaLock Push-to-Connect Fittings |
| Fitting Type | Reducing Stackable Valve |
| Connection Method | Push-to-connect, no tools required |
| Compatible Tubing | Copper, CPVC, PEX, LDPE, MDPE, HDPE, Polypropylene |
| Material | Engineered polymer body with stainless steel components |
| Configuration | Large diameter reducing valve with stackable design |
| Standards | CTS (Copper Tube Size) and NPT thread compatible |
Connection Steps
- Cut tubing squarely and remove burrs or rough edges with a deburring tool
- Mark the tubing insertion depth according to manufacturer guidelines
- Push tubing firmly into the AquaLock fitting until it seats completely at the internal stop
- Test connection by gently pulling on tubing to verify secure engagement
- Pressurize system gradually and inspect for leaks before full operation
Tubing & Thread Reference
The Watts AquaLock system accommodates a wide range of tubing sizes from 3/8" OD (1/4" CTS) up to 1-1/8" OD (1" CTS) for polypropylene and other flexible tubing materials. NPT threaded connections range from 1/4" NPT (0.540" OD) to 2" NPT (2.375" OD), providing integration with standard plumbing fixtures, filtration housings, and water treatment equipment. CTS sizing corresponds to copper tube inside diameter standards, while NPT provides tapered thread compatibility for valves, manifolds, and tees.
