Hose Nipple 9 mm, BRADAS brass, GZ 1/2" male (model 99937)

BRADAS hose nipple 9 mm (model 99937) is a brass connector designed to join hoses with a 9 mm inner diameter to fittings with a 1/2" male thread. Manufactured from brass, the nipple resists corrosion and provides a tight mechanical connection between flexible tubing and standard threaded ports. Its compact design suits garden, irrigation and general water supply assemblies where a small-diameter hose must be adapted to a 1/2" threaded fitting.

Advantages

The brass construction offers good resistance to corrosion and wear, ensuring a longer service life compared with many plastic alternatives. The 9 mm barbed end secures the hose mechanically, reducing the need for complex adapters, while the 1/2" male threaded end matches standard threaded fittings for a reliable seal. Compact dimensions and rigid material provide stable alignment and simple installation in confined spaces.

Suitable for

• Connecting 9 mm inner-diameter flexible hoses to 1/2" threaded garden taps and fittings
• Irrigation lines and drip systems requiring a transition to standard threaded ports
• Small water supply assemblies, workshop or hobby plumbing where space is limited
• Temporary or permanent connections in outdoor and indoor non-pressurized applications

Key specifications

• Material: brass for corrosion resistance
• Hose barb diameter: for 9 mm inner-diameter hose
• Thread type: 1/2" male threaded end compatible with standard 1/2" fittings
• Connection style: barbed hose end and threaded male end
• Typical applications: garden hoses, irrigation systems, small water lines

How to use

Select a hose with a 9 mm inner diameter and slide it over the barbed end until the hose seats against the shoulder. For a secure mechanical joint, fit a suitable hose clamp over the hose and tighten evenly. Screw the 1/2" male threaded end into the mating 1/2" female fitting by hand, then tighten gently with appropriate tools until snug, taking care not to over-tighten and deform threads. Inspect the connection for leaks before full use.

Usage recommendations

Use with compatible 9 mm hoses and avoid aggressive chemicals that may attack brass. For pressurized or permanent installations, pair the barb connection with a stainless-steel or quality hose clamp and apply thread sealant or PTFE tape on the 1/2" male thread when required by the application. Periodically check connections for corrosion or loosening in outdoor installations.
