Product information

Description

The Rockforce threaded adapter RF-MFE04/06 converts a M1/4" male thread to a F3/8" female thread, enabling connection between components with different thread standards. This compact metal adapter is designed for use in pneumatic, hydraulic and workshop fittings where a reliable thread transition is required. Its small size makes it suitable for on-site repairs, retrofitting tools or joining hoses and connectors without replacing existing parts.

Advantages

The adapter provides a precise and stable mechanical connection between M1/4" male and F3/8" female threaded components. Manufactured to deliver consistent thread engagement, it reduces downtime during maintenance and simplifies the adaptation of fittings. Its compact form factor allows installation in tight spaces, and the solid construction ensures durability under standard workshop and industrial conditions.

Suitable for

Adapting pneumatic fittings and air tools
Connecting hydraulic hoses and small fluid lines (where compatible)
Workshop repairs and retrofits of connectors and couplings
Temporary or permanent thread transitions in maintenance operations

Key specifications

Input thread: M1/4" male
Output thread: F3/8" female
Function: Thread conversion between differing thread standards
Application areas: Pneumatic, hydraulic and general workshop fittings
Form factor: Compact inline adapter suitable for confined spaces

How to use

Ensure both mating threads are clean and free of debris before installation. Hand-start the M1/4" male end into the mating female thread, then tighten to a secure fit using appropriate tools; avoid over-torquing to prevent thread damage. After connecting the F3/8" female end to the corresponding male component, check for proper seating and, if applicable, perform a leak or pressure test suitable for the system. Use thread sealant or tape only if required by the application and compatible with the media being conveyed.

Usage recommendations

Verify material compatibility and pressure ratings of the connected components prior to use. For high-pressure hydraulic systems or critical applications consult system specifications or a qualified technician to confirm the adapter is appropriate. Regularly inspect threaded connections for wear, corrosion or loosening during routine maintenance.
