Product Introduction

Forged cast iron fittings with 220 equal diameter socket. Some markets refer to it as a pipe clamp. For couplings, we have full thread couplings and parallel thread couplings. According to weight, we have three types of couplings: heavy-duty belt couplings with UL/FM certification, medium-sized belt couplings without UL/FM certification, and lightweight bead type. According to surface treatment, it can be divided into hot-dip galvanized joints, cold dip galvanized joints, and blackened joints. These connectors can be made with NPT threads and BSP threads.
