Is the Collet for Hydraulic Hoses 4SH, R13, R15, Carbon Steel, IL4 Type compatible only with INTERLOCK fittings?

Collet for Hydraulic Hoses 4SH, R13, R15, Carbon Steel, IL4 Type is engineered exclusively for use with INTERLOCK hydraulic fittings from the same supplier, so it is compatible only with INTERLOCK fittings. The IL4 sleeve’s design, machining requirements and dimensions are matched to INTERLOCK fittings to ensure precise fit, secure clamping and maximum safety; using it with non‑INTERLOCK fittings may result in improper fit and compromised performance.

Can the Collet for Hydraulic Hoses 4SH, R13, R15, Carbon Steel, IL4 Type be used with hydraulic fittings from other manufacturers if specifications match?

Collet for Hydraulic Hoses 4SH, R13, R15, Carbon Steel, IL4 Type is engineered exclusively for use with INTERLOCK hydraulic fittings from the same supplier. Even if another manufacturer’s fittings match the nominal dimensions (D1, D2, D3) and appear compatible, using the IL4 collet with third‑party fittings is not recommended. The IL4’s design, tolerances, and requirement for both external and internal machining during assembly are matched to INTERLOCK fittings to ensure a precise seal, correct clamping engagement and safe performance under high pressure. Subtle differences in thread form, shoulder geometry, material hardness or machining tolerances between manufacturers can compromise fit, cause leaks, premature wear or failure, and may void warranties or safety approvals. If you consider cross‑use, obtain written confirmation from both suppliers that their components are fully compatible and meet the same specifications and assembly procedures; otherwise use IL4 only with INTERLOCK fittings.
