Made from high-strength, corrosion-resistant PVC, it withstands temperatures up to 140°F and meets rigorous ASTM and NSF standards, making it ideal for industrial, chemical, and potable water applications. ## Description This Spears 836 series schedule 80 PVC adapter has a socket opening on one end and male NPT threads on the other, and is suitable for connecting pipes or fittings with different end types. The socket end connects to pipes with a smooth bore for enhanced flow, and the National Pipe Taper (NPT) threads create a tighter seal than straight threads. This adapter is made of gray PVC (polyvinyl chloride) for chemical and corrosion resistance, high strength, and less weight than fittings made from metal. 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, 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 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. The company, founded in 1969 and headquartered in Sylmar, CA, meets International Organization for Standardization (ISO) standard 9001. Review: #1 Product - Spears products are always top quality.

Its a fitting what more can I say. ### ⭐⭐⭐⭐ quality product - NPT threads quite hard *by A***N on October 6, 2014* used to fit Rainbird anti-syphon valves onto pipes in an otherwise BSF-standard irrigation system; of course the 1 inch threads fit, but didn't compress easily (into compatible Rainbird NPT socket, with 1 Teflon tape wrap + a heavy wrench) - perhaps that's a Rainbird issue. ## Frequently Bought Together - Spears 836 Series PVC Pipe Fitting, Adapter, Schedule 80, 1" Socket x NPT Male - Spears 806 Series PVC Pipe Fitting, 90 Degree Elbow, Schedule 80, 2" Socket - Spears 801 Series PVC Pipe Fitting, Tee, Schedule 80, 1" Socket --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/4826001-spears-836-series-pvc-pipe-fitting-adapter-schedule-80-1](https://www.desertcart.co.uk/products/4826001-spears-836-series-pvc-pipe-fitting-adapter-schedule-80-1) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-15*
