Overview

Product Overview

The Hydraulic Hose Fittings by Quanyi Rubber are high-precision fluid connector components engineered for secure, zero-leakage integration with hydraulic hose assemblies. Designed to withstand continuous high pressure, heavy mechanical vibration, and dynamic pressure spikes, these couplings are essential for hydraulic power systems across earthmoving, mining, and manufacturing equipment.

Manufactured using CNC precision machining from premium carbon steel (12L14/C45) or stainless steel (SS304/SS316), each fitting features precise thread profiling and smooth sealing surfaces. Our comprehensive product line includes interlocking crimp fittings, bite-type tube fittings, flange ends, and quick-connect adapters, fully compatible with braided (1SN/2SN) and spiral steel wire (4SP/4SH) hydraulic hoses.

To ensure long-lasting protection against harsh outdoor weathering and aggressive hydraulic fluids, our steel fittings undergo an advanced Zinc-Nickel (Zn-Ni) electroplating surface treatment. This provides superior rust resistance, meeting and exceeding 720-hour red rust salt spray tests (ASTM B117). Adhering strictly to international standards including SAE, ISO, DIN, BSP, JIC, and JIS, Quanyi hydraulic fittings guarantee perfect interchangeability and seamless fluid system assembly.

FAQ

Frequently Asked Questions

What thread types are available for your hydraulic hose fittings?

We offer a complete range of global standard threads, including JIC 37° flare, NPT male, BSPP/BSPT, DIN 24° cone (DKL/DKOS), ORFS flat face, and SAE Code 61/62 flanges.

What surface treatment is used to prevent rust on your fittings?

Our carbon steel fittings feature an advanced Zinc-Nickel (Zn-Ni) plating that exceeds 720 hours of salt spray testing per ASTM B117 standards.

Are one-piece pre-crimped fittings or two-piece fitting/ferrule combinations better?

Two-piece fittings (stem + ferrule) offer greater flexibility for custom hose assembly, while one-piece crimp fittings simplify fast production. We supply both types.

What working pressure ratings do these hydraulic couplings support?

Depending on thread type and size, our fittings support operating pressures up to 420 Bar (6000 PSI) with a 4:1 pressure safety factor.

Can you manufacture custom hydraulic adapters or non-standard fittings from drawings?

Yes, we offer full OEM/ODM manufacturing based on technical drawings, samples, or specific equipment requirements.
