Rain Bird X14139 Cap O-ring

Product Description

The RAIN BIRD X14139 is a replacement cap O-ring designed for use with Rain Bird quick-check valve assemblies. O-rings serve as the primary seal between the cap and valve body, preventing leakage at the service point and maintaining system pressure integrity. This component is a wear item that is typically replaced during routine valve maintenance or whenever the cap is removed and a damaged or hardened seal is discovered. Licensed irrigation technicians and experienced DIYers performing sprinkler system service are the primary installers of this part.

This O-ring is suited for residential and light commercial irrigation systems that use compatible Rain Bird valve components. It is commonly encountered during end-of-season blowouts, spring startups, or troubleshooting calls where a compromised seal is causing dripping or pressure loss at the valve cap. Having replacement O-rings on hand reduces downtime during service visits.

Compatibility

Designed as an OEM-style replacement O-ring for Rain Bird quick-check valve cap assemblies. Verify fitment against your existing valve model before ordering.

Installation Notes

Irrigation technicians should shut off the system water supply and relieve line pressure before removing the valve cap. Inspect the seating surface for debris or damage before installing the new O-ring. Lightly lubricating the O-ring with a silicone-based grease aids installation and extends seal life. Do not use petroleum-based lubricants, as they can degrade rubber compounds.
