Hydraulic Hose Fittings | NPT / JIC / BSP / Metric / ORFS - HAND HYDRAULIC

When it comes to hydraulic systems, precise thread matching and reliable sealing are the keys to stable operation. At HAND HYDRAULIC, we understand that different regional and equipment standards demand dedicated solutions. That’s why we offer a full range of hydraulic hose fittings covering all major global thread standards, to keep your fluid systems connected and leak-free.

Our Complete Thread Standard Coverage

NPT Thread (American Taper Pipe Thread)

• Key Features: 60° tapered thread with self-sealing via thread interference, no additional seal required. Excellent pressure and vibration resistance.

• Best For: North American standard hydraulic equipment, construction machinery, petrochemical pipelines, and general high-pressure fluid systems.

JIC Thread (American Flared Tube Thread)

• Key Features: 37° flared cone seal, relying on metal-to-metal contact for leak-tight connections. Reusable without damaging the sealing surface, with strong shock and vibration resistance.

• Best For: American-style hydraulic systems, agricultural machinery, and equipment requiring frequent maintenance.

BSP Thread (British Standard Pipe Thread, including BSPP/BSPT)

• Key Features: BSPP (parallel) uses an O-ring for face sealing; BSPT (tapered) seals via thread taper. Compatible with all British standard equipment.

• Best For: European/Asian hydraulic machinery, water treatment, chemical, and food-grade fluid systems.

Metric Thread

• Key Features: Standard 60° metric threads, paired with ED rings or bonded washers for face sealing. Simple, cost-effective, and widely used in domestic/European general hydraulic equipment.

• Best For: Chinese construction machinery, machine tool hydraulic systems, and general industrial equipment connections.

ORFS Thread (O-Ring Face Seal)

• Key Features: UN/UNF threads with O-ring face sealing, eliminating metal-to-metal wear. Fully reusable, with superior leak prevention even under high pressure. The ultimate choice for zero-leak hydraulic systems.

• Best For: High-end American hydraulic systems, construction machinery, injection molding machines, and high-pressure hydraulic power units.

Why Choose HAND HYDRAULIC Hydraulic Hose Fittings?

1. Full-Size Stock Availability

   We keep a complete inventory of common sizes from 1/4" to 2", and metric ranges from M10 to M42, across all NPT/JIC/BSP/Metric/ORFS standards. No long lead times—fast delivery to meet your project needs.

2. Reliable High-Pressure Performance

   Manufactured from high-strength carbon steel or stainless steel, our fittings are forged as one piece and tested under strict burst and impulse pressure conditions to eliminate leaks and ensure long-term durability.

3. Universal Hose Compatibility

   The precision-machined barbed ends provide a secure grip for braided or spiral-wire hydraulic hoses. They are engineered for maximum pull-out resistance to prevent hose blow-offs.

4. Customization Available

   Special sizes, non-standard threads, and custom finishes (zinc plating, nickel plating, stainless steel passivation) are available to meet your unique application requirements.

Ideal Applications

• Construction & agricultural machinery

• Industrial automation & machine tools

• Petrochemical & marine engineering

• Equipment maintenance & system upgrades

• High-pressure hydraulic systems with strict zero-leak requirements

At HAND HYDRAULIC, we don’t just supply fittings—we deliver the peace of mind that comes with a perfectly matched connection.
