Parker 12337 Female to Male Hose Fitting 3/4x3/8 Brass

Product Description

The PARKER 12337 is a brass garden hose fitting that connects a female hose thread to a male hose thread in a 3/4 x 3/8 inch configuration. This type of adapter is used when transitioning between two different hose thread sizes in a plumbing or irrigation assembly. The all-brass construction provides corrosion resistance and durability under standard water service conditions. Plumbers, irrigation technicians, and experienced DIYers install this fitting when a direct thread-size match is not available between two hose connections. The compact form factor makes it suitable for tight installations where space around the connection point is limited.

This fitting is appropriate for residential and light commercial plumbing applications involving garden hose thread connections. Typical use cases include irrigation system hookups, outdoor spigot extensions, portable equipment connections, and hose-to-pipe assemblies where a 3/4 inch female hose thread must mate with a 3/8 inch male hose thread. It is sold individually and intended as a single-unit replacement or assembly component.

Key Features

• Female hose to male hose thread configuration for size-transition connections
• 3/4 x 3/8 inch thread sizes to adapt between common hose and pipe dimensions
• Brass construction for corrosion resistance in water service environments
• Compact design suitable for installations with limited clearance
• Single-unit packaging for replacement or one-off assembly use

Compatibility

Designed as an OEM-style replacement fitting for standard garden hose thread assemblies requiring a female 3/4 inch to male 3/8 inch hose thread transition.

Installation Notes

This fitting is typically installed by a licensed plumber or irrigation technician. Shut off the water supply completely before disconnecting or installing any hose fittings. Apply thread sealant tape to male threads per standard practice before making the connection. Hand-tighten first, then snug with a wrench — avoid over-tightening brass fittings, as this can crack the body.
