The SHARKBITE/CASH ACME 65728B is a 1/2 inch OD flare x 1/2 inch female iron pipe (FIP) gas adapter fitting constructed from zinc-plated steel. It bridges a flared gas connector to a threaded female port, making it a standard transition piece in residential gas piping systems. The flared end accepts the nut of a flexible gas connector, while the FIP end threads onto an appliance inlet, gas ball valve, or gas supply stub-out. Licensed plumbers and gas fitters install this fitting during appliance hookups, gas line rough-ins, and service calls where a flare-to-FIP transition is required. The zinc-plated steel construction resists corrosion in typical indoor gas service environments.
This fitting is suited for residential gas appliance connections including ranges, dryers, water heaters, and other gas-fired equipment that terminate with a 1/2 inch FIP inlet. It is commonly used to connect a flexible gas connector to a wall stub-out or shutoff valve with a female threaded port. The adapter is sold in a package of 6 units, making it practical for plumbing supply stock or multi-unit service work. Installation follows standard natural gas or propane piping practices as governed by applicable local codes and the International Fuel Gas Code (IFGC).
Designed as a standard flare-to-FIP gas adapter for residential gas appliance connections where a 1/2 inch OD flare connector mates to a 1/2 inch female iron pipe threaded port on an appliance inlet, gas ball valve, or supply stub-out.
Installation must be performed by a licensed plumber or qualified gas fitter in accordance with local codes and the IFGC. Shut off the gas supply at the meter or service valve and verify zero pressure before making or breaking any connection. Apply an approved pipe thread sealant or tape rated for gas service to the FIP threads only — never apply sealant to the flare seating surface. After assembly, test all joints for leaks using an approved gas leak detection solution before restoring gas service.
