High-Performance Connectors for Fire & Industrial Applications

Every coupling is precision-machined with tight tolerances and robust locking mechanisms to eliminate leaks under pressure. All products undergo strict testing to ensure they meet safety standards, protecting personnel and preventing costly fluid loss in critical applications.

From fire hose couplings to industrial liquid transfer connectors, we offer tailored solutions for diverse needs. Whether you require special sizes, thread types, or surface treatments, our OEM/ODM service delivers couplings optimized for your specific industry and working conditions.

Our couplings meet strict international specifications including BS336, DS 2701, DIN 14306, and more. Designed for full compatibility with standard hoses and equipment, they offer seamless interchangeability for quick, leak-free connections worldwide.

Built with premium-grade light alloy aluminum, brass, and 316 stainless steel, our couplings are engineered to withstand harsh environments, high pressures, and frequent use. They resist rust, corrosion, and wear, ensuring long-term reliability in fire fighting, marine, and industrial piping systems.

Large batch of aluminum Storz and BS336 couplings finished inspection for European clients, ready for shipment to European customers.

Our factory has recently finished a bulk order of aluminum Storz and BS336 standard fire hose couplings.All products have passed strict dimensional checking, pressure testing and leakage testing before delivery.

All our fire and industrial quick couplings pass strict pre‑shipment quality tests.

We inspect dimensions, finish, tightness, pressure resistance and leak‑proof performance for aluminum, brass and stainless steel products under standardized procedures, complying with international standards.

Rigorous QC ensures reliable performance in firefighting, fluid transfer and outdoor applications.

Our team attended Frankfurt International Fire Equipment Exhibition, showcasing Storz, BS336, NPT and custom fire & industrial quick couplings.

We met over 80 global buyers, earned high recognition, and secured 12 cooperation intentions for aluminum/stainless steel couplings.

We will expand global partnerships via exhibitions. Contact us for quotations and custom solutions.
