This fitting features right-hand threading, the standard thread orientation used across the vast majority of pipe installations. Finished in black, this coupling is commonly associated with black iron pipe systems used in gas distribution and similar applications. Each package contains 10 couplings, making it practical for jobs requiring multiple fittings. Licensed plumbers and pipefitters are the primary installers of this type of fitting.\u003c\/p\u003e\n\u003cp\u003eThis coupling is suited for 3\/8-inch threaded pipe applications in residential and light commercial settings. Typical uses include gas supply lines, general plumbing rough-in, and industrial piping where black iron fittings are specified.
