Machine Fitment & Industrial Use

Use for compatible pneumatic, vacuum, automation, climate-control, and equipment-service circuits where a 1/4 in OD tube x 1/8 in MNPT push-to-connect fitting is required.

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.

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.

• 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

Brass Hose Adapter | 1/4 SAE Male x 5/16 SAE Female is a brass hose and service adapter for compatible HVACR, refrigeration, mini-split, service-tool, and industrial hose connections. 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 hose/service adapter.

• End style: flared ends for HVACR service use.

• Connection path: 1/4 in SAE male x 5/16 in SAE female.

• Input connection size: 5/16 in.

• Output connection size: 1/4 in.

• Overall length: 1-3/8 in.

• Temperature range: 0 Degrees F to 122 Degrees F.

• Use family: HVACR, mini-split, ductless, refrigeration, and service-tool connections where the hose and port match.

• Service fit: useful where a service hose, manifold, gauge hose, or mini-split service connection requires the listed SAE conversion.

• Selection checkpoint: SAE flare connections seal differently than pipe-thread fittings, so match the port style and sealing surface rather than choosing by diameter alone.

• Ordering check: verify refrigerant/service application, SAE thread form, sealing surface, pressure rating, service-tool compatibility, and installed clearance before ordering.

Related Parts & Compatibility Notes

• Do not substitute for pipe-thread adapters, push-to-connect fittings, compression fittings, or dry-cleaning machine valve fittings unless every connection and service condition matches.

• Use only where the service hose and service port match the listed SAE connection path.

• If the hose end, gauge manifold, or service port uses NPT, compression, push-to-connect, or another thread family, choose a different fitting.

Machine Fitment & Industrial Use

Use for compatible refrigeration and HVACR service work where a 1/4 in SAE male to 5/16 in SAE female adapter is required.

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.
