Multi-Lug LDH Female Thread Adapter | Custom Size, Pressure & Connection

Our Multi-Lug LDH Female Thread Adapter is a special transition fitting for large-diameter remote fire water supply pipelines. It bridges LDH multi-lug hose couplings and threaded valves, pumps, pipes or other fixed fire equipment, realizing fast conversion between lug connection and threaded connection.

It is manufactured from high-strength forged A6061 aluminum alloy, with excellent impact resistance and pressure bearing capacity. The multi-lug side uses the same symmetrical genderless locking design as standard LDH couplings, compatible with all matching LDH fittings and operable with gloved hands. Precision machined internal thread guarantees smooth assembly. Built-in NBR rubber gasket delivers stable sealing to avoid water leakage and pressure drop during water delivery.

Customization is available for your project: thread standard (BSP, NPT etc.), inner bore size, working pressure rating, lug dimension, surface finish and laser marking.

Widely used in fire rescue, petrochemical fire protection, mine drainage and municipal emergency water transfer. Every unit will pass hydraulic pressure testing before shipment. OEM & ODM are welcome. Send your drawing or specs for quotation.
