Jaco - Male Connector Fitting with Ferrule Nut and Integral Sleeve - Polypropylene
Male Connector Fitting with Ferrule Nut and Integral Sleeve
The Jaco male connector with ferrule nut provides a reliable NPT threaded connection for soft plastic tubing in residential and light commercial water filtration systems. Constructed from polypropylene with excellent chemical resistance, this fitting features an integral sleeve design for secure tube retention up to 50 PSI in standard sizes.
Technical Details
| Material | Polypropylene (NSF 61 Listed) |
| Thread Type | National Pipe Thread (NPT) |
| Pressure Rating | 50 PSI (1/8"–1/2"), 220 PSI (5/8" and up) |
| Temperature Range | -30°F to 215°F |
| Application | Soft plastic tubing, low pressure systems |
| Enhanced Pressure | Add gripper for 220 PSI rating |
Understanding National Pipe Thread Measurements
NPT fittings do not measure their nominal size when placed against a ruler. The actual outside diameter is larger than the fractional designation. For accurate identification, measure the thread diameter and reference the table below.
| NPT Size | Actual Diameter |
| 1/8" NPT | 0.405" |
| 1/4" NPT | 0.540" |
| 3/8" NPT | 0.675" |
| 1/2" NPT | 0.840" |
Where This Fitting Works
Jaco polypropylene male connectors are designed for residential reverse osmosis systems, under-sink filter installations, water softeners, and light commercial filtration equipment using soft plastic tubing. The NSF 61 listing certifies the material for potable water contact. Compatible with polyethylene, PVC, and other flexible tubing materials in both municipal and well water applications.
Jaco fittings have been the standard in water treatment connections for decades, trusted by installers who need components that seal properly the first time.
