Coilhose Pneumatics 6-306 Straight Pneumatic Coupler 3/8 in

Product Description

The COILHOSE PNEUMATICS 6-306 is a straight pneumatic hose coupler designed for use in compressed air systems where reliable, leak-free connections are required. Built from brass, this coupler features a 3/8-inch body diameter and a hose barb thread type, making it a direct-connect solution for hose-to-fitting assemblies. It follows the Moldflow interchange standard, ensuring cross-compatibility with other Moldflow-pattern couplers in the field. This type of coupler is typically installed by industrial maintenance technicians, equipment service professionals, and pneumatic system installers working with air tools, compressors, and related equipment.

The 6-306 is suited for straight-run pneumatic hose connections in both light industrial and workshop environments. The hose barb design accommodates 3/8-inch inside diameter hose, providing a secure mechanical grip when the hose is pushed onto the barb and secured. It is appropriate for use in air tool circuits, pneumatic control lines, and general compressed air distribution where Moldflow-style couplers are specified. This coupler is sold individually and is a standard catalog item for service and maintenance applications.

Key Features

• Brass construction for corrosion resistance and durability in compressed air service
• 3/8-inch body diameter matches common pneumatic hose and fitting standards
• Moldflow interchange pattern for compatibility with other Moldflow-style couplers
• Hose barb thread type provides a secure, push-on connection to 3/8-inch ID hose
• Straight coupler configuration for in-line hose assembly without directional offset

Compatibility

Designed as an OEM-style replacement or service coupler for pneumatic systems using Moldflow interchange couplers with 3/8-inch body diameter and 3/8-inch inside diameter hose barb connections.

Installation Notes

Installation is typically performed by pneumatic system technicians or industrial maintenance personnel. Always depressurize and bleed the air line completely before disconnecting or installing any pneumatic coupling. Ensure the hose inside diameter matches the 3/8-inch barb before assembly, and secure the hose with an appropriate clamp to prevent blowoff under pressure. Follow applicable OSHA and local safety codes for compressed air systems during installation and testing.
