Pneumatic hose tail with external 1/4" thread PARTNER PA-MH04/08, 12 mm 'herringbone' fitting

Pneumatic hose tail PARTNER PA-MH04/08 features an external 1/4" threaded connection combined with a 12 mm herringbone barbed end designed for secure attachment of hoses used in air and pneumatic systems. This metal fitting allows a threaded port or component to be connected to a 12 mm internal-bore hose, providing a compact transition between threaded equipment and flexible tubing in workshops and industrial installations.

Advantages

The combination of an external 1/4" thread and a 12 mm herringbone barb ensures a firm mechanical hold and improved hose retention under pressure. The simple, compact design reduces leak points and eases installation in confined spaces. Constructed for pneumatic applications, the fitting tolerates standard workshop handling and repeated assembly and disassembly while maintaining a reliable seal when used with appropriate clamps or crimp rings.

Suitable for

• Connecting flexible 12 mm internal-bore hoses to 1/4" threaded pneumatic ports
• Workshop air lines and compressed-air tools
• Industrial pneumatic circuits and maintenance tasks
• Retrofit or repair of existing pneumatic fittings and hose assemblies

Key specifications

• Thread type: external 1/4" (1/4 inch) threaded male connection
• Hose connection: 12 mm herringbone (barbed) tail for internal-bore hoses
• Application: pneumatic and compressed-air systems
• Design: compact hose tail for direct hose-to-thread transition

How to use

Insert the 12 mm herringbone barb into the hose end until it seats fully on the barb profile. Secure the hose onto the barb with an appropriate clamp or crimp ring sized for a 12 mm hose to prevent blow-off under pressure. Screw the external 1/4" threaded end into the corresponding female threaded port using suitable thread sealant or tape if required by the application. Tighten to a firm hand-plus wrench setting; avoid over-tightening which can damage threads or deform the fitting.

Usage recommendations

Use hose clamps rated for pneumatic pressure and inspect connections periodically for wear, hose aging or loosening. Match the hose inner diameter and material to the barbed tail and the system's operating pressure and media to ensure a safe, leak-free connection.
