What Are Metric Interlock Fittings?

Metric interlock fittings are hydraulic hose fittings designed with Metric thread standards and interlock crimping structures for high-pressure hydraulic hose assemblies.

The interlock design mechanically locks the fitting with both the inner and outer layers of the hydraulic hose, significantly improving hose retention strength and operational safety in demanding hydraulic systems.

Metric hydraulic fittings are widely used in hydraulic systems designed according to DIN and ISO standards, especially in European hydraulic equipment and industrial machinery.

Metric interlock hose fittings are commonly applied in:

• Construction machinery

• Agricultural equipment

• Mining machinery

• Industrial hydraulic systems

• Material handling equipment

• Injection molding machines

• Heavy-duty transportation equipment

Main Features of Our Metric Interlock Hydraulic Fittings

Designed for High-Pressure Applications

Our Metric interlock hose fittings are suitable for ultra-high-pressure hydraulic systems using multi-spiral hydraulic hoses.

Strong Interlock Crimping Structure

The interlock mechanism enhances hose retention performance and reduces the risk of hose blow-off during pressure surges.

Precision Metric Thread Machining

Accurate Metric thread processing ensures stable sealing performance and leak-free hydraulic connections.

Corrosion-Resistant Surface Treatments

Available surface finish options include:

• Zinc plated hydraulic fittings

• Cr6-free plating

• Nickel plated hydraulic fittings

• Stainless steel Metric fittings

These finishes improve durability in harsh industrial environments.

Compatible with Various Hydraulic Hoses

Suitable for:

• SAE 100R12 hose

• SAE 100R13 hose

• SAE 100R15 hose

• Spiral hydraulic hoses

• High-pressure rubber hoses
