Carbon Hydraulic Sleeve

DIN 2353 and ISO 8434-1 compliant, the XYOON Carbon Hydraulic Sleeve is a precision bite-type component for compression tube fittings. When axially compressed, it bites into the tube wall to form a permanent, vibration-resistant metal-to-metal seal at pressures up to 630 bar. Available in zinc-plated carbon steel with 500+ hours salt spray resistance, and black phosphate for high-temperature applications. Fully interchangeable with global brands, supports 2-3 times reassembly. Factory direct with bulk supply.

Product Definition & Function

Carbon Hydraulic Sleeves are precision-machined bite-type components used in compression tube fittings. Working with fitting bodies and nuts, they radially deform under axial compression to bite into seamless steel tube walls, creating a permanent, vibration-resistant, leak-tight metal-to-metal seal without welding. Fully compliant with DIN 2353 (L and S series) and ISO 8434-1 standards, they are the core sealing element for high-pressure hydraulic tube connections.

Core Advantages of Carbon Hydraulic Sleeve

·  High pressure rating: Matches DIN 2353 L (light) and S (heavy) series, working pressure up to 630bar

·  Reliable bite performance: Precision ground cutting edge, uniform bite depth, zero pull-off under rated pressure

·  Stable anti-corrosion: Standard 8–12μm zinc-plated surface, 500+ hours salt spray resistance

·  Reusable assembly: Supports repeated disassembly and reassembly for pipeline maintenance

·Full interchangeability: Fully compatible with DIN/ISO standard compression fittings from global brands
