Detail

We supply couplings for distributors, wholesalers, contractors, and industrial buyers. We manufacture carbon steel merchant couplings available for bulk orders.

Merchant Couplings

“Merchant” represents couplings manufactured from carbon steel.

The carbon steel pipe coupling conforms to ASTM A865 and ANSI B1.20.1 thread standards.

It differs from malleable iron couplings by material. Merchant couplings include full and half couplings.

It is used for lower pressure. Tapered threads provide a tighter, more secure seal than straight threads.

Buyers should confirm whether tapered or straight pipe threads.

Full & Half Couplings

Full couplings have female threads on the inner side and a standard length. Half couplings are shorter than full pipe couplings.

The right type depends on the connection required, so confirm the coupling types, size, and thread specification first.

Carbon Steel Coupling & Standards

Our carbon steel pipe coupling is available for industrial, utility, and mechanical applications. Carbon steel offers a practical combination of strength, machinability, durability, and cost.

Depending on the market, specifications include ASTM, ASME, ANSI, DIN, EN, or BS. Thread standards such as NPT, BSPT, or BSPP.

For galvanized couplings, confirm the required zinc coating and applicable specification.
