Crimping Hydraulic Sleeve

Crimping Hydraulic Sleeve are cylindrical metal fittings that work with matching hose stems and hydraulic hoses. When compressed by a crimping machine, the sleeve deforms evenly to lock the hose between the sleeve and stem, forming a permanent pressure-resistant connection.

● Replaces unreliable hose clamps for high-pressure applications

● Maintains stable sealing under impulse pressure and mechanical vibration

● Fully compatible with standard hydraulic hose stems per SAE and DIN norms

Core Advantages

Precision dimensional control: Inner diameter tolerance±0.05mm, ensures uniform crimp deformation and consistent pull-out strength

High pressure rating: Matches 1SN/2SN braided hoses and 4SP/4SH spiral hoses, working pressure up to 600bar (8700PSI)

Reliable anti-corrosion: Standard 8–12μm zinc plating with 500+ hours salt spray resistance; black phosphate and stainless steel options available

Hose-friendly design: Smooth inner chamfer protects the hose outer layer from damage during assembly, extends hose service life

Universal interchangeability: Fits standard hose stems from mainstream global brands, no compatibility barriers
