Swivel Seal Kit, 1/2In Viton O-Ring

Description

Coxreels 439-1 Swivel Seal Kit is a maintenance kit designed to restore leak-free performance to Coxreels ½" NPT swivel joints. Supplied with precision-engineered Viton O-rings and supporting PTFE backing rings, it’s ideal for replacing worn or degraded seals in spray, fluid, or hose reel assemblies. 

Key Features & Components

• Seal Material: High-grade Viton (FKM) O-rings offering excellent resistance to chemical, heat, and aging factors.
• Backing Rings: Includes PTFE (Teflon) rings to support low-friction operation and seal integrity under pressure.
• Compatibility: Fits Coxreels swivel models in the 439 series (e.g., 439, 439-1, 439-3) with ½" NPT connections.
• Kit Contents: Typically includes two Viton O-rings and two PTFE backing rings (or similar configuration).
• Maintains Pressure Rating: When installed correctly, the kit helps the swivel maintain its original performance and pressure rating (as designed by Coxreels).

Applications & Use Cases

• Ideal for repair and preventive maintenance on hose reels and spray systems that use a ½" swivel joint
• Use in agricultural sprayers, fluid dispensing systems, pressure washers, or any system where a Coxreels swivel is employed
• Replacement for leaking or worn seal systems to avoid downtime and fluid loss
• Useful in settings requiring chemical resistance — the Viton components stand up to many industrial fluids better than standard rubber 

Benefits

• Restores leak-proof operation without needing full swivel replacement
• Chemical & temperature resistant seals extend service life in harsh environments
• Cost-effective maintenance kit to prolong the life of hose reel systems
• Precise fit prevents over-tightening or misalignment, protecting the swivel body
