These were used on a water leak detection system briefly before being stored. A whole assortment of mostly 1/4” and some 1/8” and 3/8” NPT galvanized pipe fittings all in salvageable condition. 90’s, 45’s street, nipples, adapters, reducers’s etc, its got a least 1 everything. Could be useful for a hobbyist tinker person, steam engine train? Too small for most home use. Let me know it interests you, thanks for looking
