The DSP Adapter to Male Thread without Locking Ring is a reliable and efficient fitting designed to connect DSP-type fire hose couplings to male-threaded equipment or piping. This version omits the locking ring for simplified applications where rapid connection and disconnection are required and where a locking mechanism is not essential.
Fabricated from high-quality aluminum alloy or brass, the adapter delivers excellent corrosion resistance, mechanical strength, and compatibility with standard BSP or NPT threads. It is ideal for firefighting systems, industrial setups, and water transfer operations.
Key Features:
DSP coupling on one end, male threaded connection on the other
Available in BSP or NPT thread types (as specified)
No locking ring – suitable for fast, tool-free connections
Made from durable brass or lightweight aluminum alloy
Provides a secure and leak-free transition between systems
Commonly used in fire protection, industrial water delivery, and marine applications
Sizes typically include DSP 40, DSP 65 with threads like 1½”, 2″, or 2½”
