Midland Industries 51029 1/4 in Sch 80 Ss Pipe Nipple

Product Description

The MIDLAND INDUSTRIES 51029 is a seamless Schedule 80 pipe nipple constructed from 304 stainless steel, designed for use in plumbing, HVAC, and industrial piping systems. It features 1/4-18 NPT male threads on both ends and measures 5.5 inches in length with a 1/4-inch diameter. The SCH 80 wall thickness and seamless construction provide elevated pressure resistance, rated to 3000 psi. This nipple is installed by licensed plumbers and pipefitters in applications requiring corrosion resistance and reliable thread engagement. Dimensions conform to ANSI/ASME B1.20.1 standards.

This nipple is rated for use with air, water, oil, natural gas, and steam service, making it a versatile component in both commercial and residential systems. It is suited for high-pressure distribution lines, boiler piping, gas supply runs, and compressed air headers where stainless steel corrosion resistance is required. The 304 SS material performs reliably in wet and mildly corrosive environments, and the seamless body eliminates weld-zone weak points that could fail under cyclic pressure.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter following applicable IPC and IFGC code requirements for the service type. Shut off and depressurize the line completely before removing or installing any fitting. Apply a compatible thread sealant or PTFE tape rated for the specific service medium before making up the joint. Do not over-torque stainless steel threads, as galling can occur and damage both the nipple and mating fitting.
