Watts AquaLock - Large Diameter Reducing Stem
Large Diameter Reducing Stem
The Watts AquaLock Large Diameter Reducing Stem provides a secure, tool-free connection between different tubing diameters in residential and light commercial plumbing applications. Compatible with copper, CPVC, PEX, LDPE, MDPE, HDPE, and polypropylene tubing, this reducing stem simplifies complex installations and reduces leak points. Push-to-connect design allows for quick assembly and disassembly without cutting or soldering.
Polypropylene and Copper Tube Compatibility
| Polypropylene Tubing (OD) | Copper Tube Size (ID) |
|---|---|
| 3/8" OD | 1/4" CTS |
| 1/2" OD | 3/8" CTS |
| 5/8" OD | 1/2" CTS |
| 7/8" OD | 3/4" CTS |
| 1-1/8" OD | 1" CTS |
NPT Pipe Thread Reference
| OD Actual (inches) | NPT Thread Size |
|---|---|
| 0.540" | 1/4" NPT |
| 0.675" | 3/8" NPT |
| 0.840" | 1/2" NPT |
| 1.050" | 3/4" NPT |
| 1.315" | 1" NPT |
| 1.660" | 1-1/4" NPT |
| 1.900" | 1-1/2" NPT |
| 2.375" | 2" NPT |
System Integration
Watts AquaLock fittings are engineered for use with copper, CPVC, PEX, polyethylene (LDPE, MDPE, HDPE), and polypropylene tubing systems. Ideal for RO system connections, point-of-use filter installations, ice maker lines, refrigerator hookups, and general plumbing transitions. CTS refers to Copper Tube Size based on inside diameter. NPT is National Pipe Tapered thread standard for male (MIP) or female (FIP) threaded connections. NPS denotes National Pipe Straight thread (IPS). MGHT is Male Garden Hose Thread.
Watts AquaLock fittings are manufactured to meet industry standards for residential and light commercial water systems.
