Western Enterprises 543 Hose Adapter 1/4 Mpt X 3/8 Barb

Product Description

The WESTERN ENTERPRISES 543 is a straight hose adapter designed to connect a 1/4-inch male pipe thread (MPT) fitting to a 3/8-inch barbed hose end. This type of fitting is a standard transition component used in gas distribution, compressed air, and fluid transfer assemblies where a threaded port must be converted to a barbed hose connection. Weighing approximately 0.1 pounds, the 543 is a compact, single-piece adapter suited for professional plumbing, HVAC, and industrial gas service applications. Licensed tradespeople and service technicians keep these adapters on hand for field repairs and new installations requiring reliable thread-to-barb transitions.

This adapter is appropriate for residential and light commercial service work where a 1/4-inch NPT male thread outlet must be terminated to a 3/8-inch barbed hose connection. Typical applications include gas appliance hookups, pneumatic tool lines, and fluid transfer systems. The adapter is sold individually but is available in a minimum order quantity of 25 units per pack, making it practical for shop stock, fleet service vehicles, and supply house resale.
