The National Pipe Taper (NPT) threads create a tighter seal than straight threads, and the socket end connects to pipes with a smooth bore for enhanced flow. This tank adapter fitting is made of gray PVC (polyvinyl chloride) for chemical and corrosion resistance, high strength, and less weight than fittings made from metal, and has a neoprene gasket for resistance to weathering, oil, and heat. It is compatible with schedule 80 (thick wall) PVC pipes and fittings, and is suitable for chemical processing, industrial plating, chilled water distribution, deionized water lines, and chemical drainage and wastewater treatment systems. PVC can be connected to other materials such as steel, copper, or cast iron using transition fittings. The fitting has a maximum operating temperature of 140 degrees F, and a maximum pressure rating of 150 pounds per square inch (psi) at 73 degrees F. It meets ASTM International D1784 and D2467 standards for quality assurance, and is certified by National Sanitation Foundation International (NSF) for potable water service. This schedule 80 PVC bulkhead tank adapter is suitable for connecting pipes for conveying drinking water, waste water, chemicals, and other liquids in a range of industries.Pipe fittings are components used for connecting, terminating, controlling flow, and changing the direction of piping in many different industries. When purchasing pipe fittings, consider the application, as this will affect material type, shape, size and required durability. Fittings are available threaded or unthreaded, in many shapes, styles, sizes, and schedules (pipe wall thickness).Spears Manufacturing produces thermoplastic fittings and valves for fluid, drain, waste, and vent systems.

It's potable water approved. I used a 2 and 5/16 hole saw and the fit is perfect. Watch out for the curvature of the tank, I don't think this bulk head would seal correctly on any tank less than 30" in diameter. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/31476281-spears-8171-series-pvc-bulkhead-tank-adapter-schedule-80-gray](https://www.desertcart.tw/products/31476281-spears-8171-series-pvc-bulkhead-tank-adapter-schedule-80-gray) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-10-10*
