This SAE J1467 Standard covers material and dimensional requirements of steel clip fastener fittings, also know as staple-lock hydraulic fittings and adaptors. These fittings are intended for use in hydraulic systems on industrial equipment primarily in mining applications.
This technical reference document applies to 420 bar super staple-lock fittings and adaptors,
which are used to connect hydraulic fluid based systems. The proposed standard seeks to clarify minimum material and dimensional requirements for a 420 bar connection, whilst maintaining a 4:1 factor of safety (FOS).
This document defines:
1. minimum working pressure of the assembled fitting (including its staple)
2. relevant testing and conformance standards
3. arrangement of components & their individual dimensions
4. material specifications for the components
5. corrosion resistance of metal components
6. identification
7. minimum burst pressure
8. impulse requirements of the assembled fitting
The related standard is interchangeable to DIN and BS as follows:
DIN 20043: Staple-Lock Couplings for Hydraulic transmission Circuits
NCB 638 and BS 6537: Specification for staple type connectors for hydraulic fluid power application
