Brass Conversion Adapter | 1/4 FIP x 5/16 MIP | 4 Pack is a brass conversion adapter set for compatible service, gauge, and equipment fitting work. This listing is written as a technical Corbett Equipment catalog listing for dry-cleaning shops, commercial utility service, equipment maintenance, water treatment, refrigeration/HVACR service, pneumatic systems, steam/gauge service, and industrial maintenance where the installed component matches the specifications below.
Use this listing only after comparing the installed part, physical dimensions, connection style, material, operating conditions, and machine or system documentation.
Technical Specifications
Component type: brass conversion adapter.
Package format: 4 adapters per pack.
Material: brass.
Connection path: 1/4 FIP x 5/16 MIP.
Connection type: female flare x male flare.
Side A: 1/4F.
Side B: 5/16M.
Use case: thread conversion where both connection standards match the installed service path.
Service fit: used when a fitting path needs a compact brass conversion between a 1/4 female flare side and a 5/16 male flare side.
Selection checkpoint: confirm the flare seat, thread form, male/female orientation, and required quantity before ordering.
Pack note: sold as a 4-pack for service work where multiple adapters may be needed for the same repair or setup.
Ordering check: verify thread size, thread type, flare sealing method, pressure, temperature, media, and installed fitting clearance before ordering.
Related Parts & Compatibility Notes
Do not confuse with SAE hose adapters, MNPT push-to-connect fittings, compression fittings, or general pipe fittings.
Use only where the installed component requires the listed female-flare to male-flare conversion path.
A visually similar brass adapter may not seal if the flare angle, thread family, or male/female orientation differs.
Warnings & Restrictions
Warning listed for this item family: Cancer and Reproductive Harm. See www.P65Warnings.ca.gov.
Verify the application, media, pressure, temperature, and local requirements before installation.
Machine Fitment & Industrial Use
Use for verified equipment-service fitting conversions where the installed service path requires 1/4 FIP x 5/16 MIP brass adapters.
For dry-cleaning equipment, verify against the actual machine, valve panel, boiler or water-treatment system, gauge assembly, filtration system, utility line, pneumatic circuit, refrigeration service port, or service hose before ordering. If the product is being used outside dry cleaning, confirm compatibility with the application and operating conditions before installation.
Installation & Ordering Verification
Compare the product photo, installed component, size, connection style, and service location before ordering.
Confirm pressure, flow, temperature, material, chemical exposure, media compatibility, clearance, and mounting for the actual system.
Use qualified service personnel when installing pressure, steam, refrigeration, water, electrical, pneumatic, or equipment-control components.
Send photos of the installed part, machine tag, and service location if fitment is uncertain.
