Thread Standards & Compatibility

JIC (SAE J514): 37° flare seating angle, widely used in North American industrial and mobile hydraulics.

ORFS (SAE J1453): O-Ring Face Seal, offering the highest level of leak protection in high-pressure, high-vibration environments.

NPT/NPTF: Tapered pipe threads that achieve a seal through metal-to-metal wedging (NPTF dry-seal eliminates the need for thread sealants in specific applications).

BSPP / BSPT (ISO 1179 / ISO 228): British Standard Pipe threads (Parallel and Tapered) with a 55° thread angle, dominant in European and Commonwealth markets.

Metric DIN (ISO 6149 / DIN 2353): 24° cone bite-type fittings, standard for European heavy industrial and automotive sectors.

Materials & Surface Treatments

Material Options

Carbon Steel (e.g., 12L14, 20#, 45#): Precision-machined for standard industrial high-pressure applications, offering excellent tensile strength.

Stainless Steel (SS316L / SS304): Essential for marine, offshore oil & gas, chemical processing, and food-grade environments where acid-base corrosion resistance is mandatory.

Brass: Ideal for low-pressure fluid transfer, instrumentation, and pneumatic systems requiring spark resistance.

Advanced Surface Coatings

To comply with global environmental standards and maximize service life, all carbon steel adapters undergo rigorous surface treatment:

Cr6-Free Zinc Plating (Zinc-Nickel Alloy): Delivers superior corrosion resistance, exceeding 720 hours of Red Rust Salt Spray Testing (ASTM B117).

Trivalent Zinc Plating: Eco-friendly finish providing over 120-240 hours of resistance to white rust.
