Description
Overview:
The 1/4" / 3/8" Left Hand M/M Hose Coupler (Manufacturer Part Number: 845 303) is a brass male-to-male reducer for joining hoses or fittings with different thread sizes where left-hand BSP connections are specified. It converts from 3/8" BSP LH (9.5 mm) to 1/4" BSP LH (6.35 mm), providing a secure, leak-resistant link in fluid or gas transfer lines. Made from durable, corrosion-resistant brass, it is suitable for demanding workshop, site, and domestic environments. With an overall length of 30 mm and an approx. body width of 20 mm, it is compact enough for tight spaces yet easy to handle during installation. Common uses include compressors, sprayers, fuel/gas lines with LH threads, and general plumbing on machinery and equipment.
Key Features:
- Converts 3/8" BSP LH (9.5 mm) to 1/4" BSP LH (6.35 mm) for mixed-size hose and fitting connections
- Male-to-male configuration for straightforward in-line coupling
- Robust brass construction for corrosion resistance and long service life
- Left-hand thread orientation to suit systems that specify reverse-thread safety fittings
- Compact form (30 mm length, 20 mm body width) for use where space is limited
- Smooth machined threads to aid sealing with appropriate washers, tape, or sealant as specified for BSP systems
- Reliable under typical workshop, site, and garden machinery conditions
- Simple to install using standard spanners for a secure, repeatable fit
- Suitable for fluid and gas transfer where LH BSP standards apply
Typical Applications:
Used to join mismatched hose or pipe threads in left-hand BSP systems on compressors, sprayers, small pumps, heaters, and certain fuel or gas lines (e.g. LPG where LH connections are specified). Helpful on construction tools, garden machinery, and workshop equipment requiring a compact reducing coupler between 3/8" and 1/4" BSP LH male fittings.
