COUPLERS, THREADS, FITTINGS & ADAPTERS IDENTIFICATION GUIDE

COUPLERS, THREADS, FITTINGS & ADAPTERS IDENTIFICATION GUIDE

Procedure

Step 1- Identification

Check couplers, threads, fittings & adapters for marking which indicates a country of origin, stamped part number or size.

America: Check NPT, JIC, UNO, ORFS Japan: Check BSP  Europe: Check DIN, BSP UK/Australia: Check JIS

Summit Hydraulics Couplers Part Number: Check AGXXF-XXS, AGXXM-XXS, AGXXF-XXN, AGXXM-XXN, AGPXXF-XXS

Summit Hydraulics Fittings Part Number: Check XXXX-XX-XX-FG, ECXX-XXS, FSXXXX-XX-XX, NXXS-XXS, HXX-XXFJ

“All Summit Hydraulic parts have a stamped indicator to aid identification”  “N-NPT, S-SAE”

Step 2- Visual Identification
Check couplers and fittings for male and/or female thread. Different features also will help identification.

• Is there an O-Ring? Washer seal?
• Are there any cone seats? Concave or convex?
• Are there any threads? Straight or tapered?
• Is the thread male or female?
• What is the style and angle of the fitting?

.

Step 3- Thread Measurement

Measure the thread diameter. We recommend a “digital caliper” tool

OD (outer diameter) – male threads

ID (inner diameter) – female threads

Step 4. Conclusion

Based on the collected measurements, match each measurements taken against the charts with similar properties to the couplers, threads, fittings & adapters. Reference step 2 to determine the properties of fittings/couplers and reference step 3 to measure fittings/couplers. Please reference next page for dimensional charts.
