Jaco - Union Connector Fitting with Ferrule Nut and Integral Sleeve - Polypropylene

The Jaco Union Connector Fitting delivers reliable, leak-free connections for soft plastic tubing in low-pressure water filtration systems up to 50 PSI. Built from NSF 61-listed polypropylene, this fitting features an integrated ferrule nut and sleeve design that simplifies installation while providing excellent chemical resistance across a wide temperature range.
SPECIFICATIONS

Technical Details

Brand Jaco

Temperature Range -30°F to 215°F
Thread Standard National Pipe Thread (NPT)
Application Soft plastic tubing connections in low-pressure water systems
Chemical Resistance Good resistance to common water treatment chemicals
INSTALLATION & USE

How to Install the Jaco Union Connector

  1. Measure your existing NPT connection using the reference guide (1/4" NPT measures 0.540" actual diameter, not 0.250"). Select the appropriate fitting size based on actual measured diameter.
  2. Slide the ferrule nut over the soft plastic tubing before inserting tubing into the connector body. Push tubing firmly into the fitting until it seats completely.
  3. Hand-tighten the ferrule nut onto the threaded body. The integral sleeve will compress evenly around the tubing to create a secure seal.
  4. Test the connection at operating pressure. For applications exceeding 50 PSI, add a Jaco gripper accessory to increase pressure rating to 220 PSI.
COMPATIBILITY

System Requirements

The Jaco polypropylene union connector is designed for soft plastic tubing in reverse osmosis systems, water filters, and other low-pressure plumbing applications. Compatible with polyethylene, vinyl, and other flexible tubing materials within the -30°F to 215°F temperature range. Not recommended for rigid piping or hard plastic tubing. NPT threading ensures compatibility with standard water filtration components and housings. The NSF 61 certification makes this fitting suitable for potable water systems.

🔧 Pro Tip: NPT fittings are tapered and measure larger than their nominal size. Always measure the actual outer diameter of your existing fitting rather than assuming the marked size. A 1/4" NPT fitting actually measures 0.540" on a ruler, which catches many first-time installers off guard.
