Hose Hydraulic Fitting

Hose Hydraulic Fittings connect flexible hoses to pumps, valves, cylinders and rigid tubing to transmit hydraulic power while absorbing vibration, thermal expansion and mechanical movement. Poorly engineered fittings often suffer from hose blow-off, seam leakage and premature corrosion, causing costly downtime and safety hazards.

XYOON hose fittings consist of a precision-machined stem and crimp sleeve. When crimped to specification, the internal barbs bite deeply into the hose reinforcement to form a permanent, high-strength mechanical interlock and leak-tight seal. Available in all major global standards, they are the reliable connection solution for flexible hydraulic lines.

Core Advantages

Anti-pull-out barb design: Optimized multi-row barb profile bites evenly into hose reinforcement. Pull-out strength exceeds hose burst strength, eliminating catastrophic blow-off failure.

Thick-wall crimp sleeve: Heavier gauge sleeve with uniform crimp deformation, no cracking or spring-back after crimping. Maintains consistent clamping force under pressure pulsation.

Precision sealing surfaces: Ground sealing cones and faces ensure leak-tight connection to mating components, with zero slow weeping under long-term vibration.

Full standard coverage: DIN 24° cone, JIC 37° flare, NPT, BSPP/BSPT and ORFS configurations, all in stock for one-stop sourcing.

Durable corrosion resistance: 8–12μm trivalent zinc plating with passivation, 500+ hours salt spray resistance for outdoor and harsh environments.

Frequently Asked Questions

Q1: What is the difference between a hose fitting and a tube fitting?

A: Hose fittings are designed for flexible rubber hoses using a crimped sleeve and barbed stem to grip the hose reinforcement. Tube fittings are for rigid metal pipes using ferrule bite or thread sealing. Hose fittings absorb vibration and movement; tube fittings provide rigid, permanent connections.

Q2: Do you provide crimping data and specifications?

A: Yes. Each Hose Hydraulic Fitting comes with matched crimp data including crimp diameter and crimp force specifications. We provide detailed crimping charts and technical documentation to ensure correct assembly with your crimping equipment.

Q3: What hose types are compatible with these fittings?

A: Our fittings are compatible with standard wire braid hydraulic hoses and spiral hoses. For specific hose brands and constructions, please consult our technical team with your hose specifications.

Q4: Can carbon steel fittings be used in marine environments?

A: Carbon steel fittings with 8-12μm trivalent zinc plating and passivation offer 500+ hours salt spray resistance, suitable for general outdoor use. For long-term marine or high-salt exposure, we recommend SS316L stainless steel fittings for maximum corrosion resistance.

Q5: What is the difference between JIC 37° and DIN 24° hose fittings?

A: JIC 37° flare is the American standard with a 37° sealing angle, widely used in North American hydraulic systems. DIN 24° cone is the German standard with a 24° sealing angle, common in European and Asian machinery. Both provide reliable metal-to-metal sealing when properly tightened.
