This valve performs well and is built to last. Made of 304 Stainless Steel with high-temperature tolerant Teflon seals, the valve is durable and can be easily dismantled for cleaning. The full-bore ball port provides excellent flow-through with almost no pressure loss, and the Weldless Bulkhead includes all the seals and lock nuts needed to install the valve in any thin-walled container. Just drill a hole 13/16" to 7/8" wide, mount the valve, and tighten the nut.Input Fitting: 0.5" Male NPTOutput Fitting: 0.5" Female NPTPort Diam.: 0.5"
