Coupling, Slip PVC Schedule 80 2" x 1" (829-249)

The 829-249 is a Schedule 80 PVC reducing slip coupling that transitions a 2-inch mainline to a 1-inch continuation or branch line via solvent cement socket connections on both ends. The 2" x 1" size pairing is one of the most commonly specified reducing coupling dimensions in industrial piping — large enough to handle meaningful flow redistribution while remaining compact enough to fit tight equipment bays, manifold assemblies, and panel-mounted pipe runs.

Schedule 80 wall thickness provides a substantially higher pressure rating and greater impact resistance than Schedule 40, making this fitting appropriate for pressurized chemical feed systems, process loops, and any application where pipe wall strength and joint integrity are non-negotiable. Both socket bores are dimensioned to accept standard Schedule 80 pipe, ensuring full solvent weld engagement and a leak-free joint when properly primed and cemented.

Gray PVC construction delivers broad chemical resistance across acids, alkalis, salts, and many industrial solvents, with no corrosion risk in wet or humid environments. This coupling conforms to ASTM D2467 dimensional standards and is manufactured from virgin PVC compound per ASTM D1784 Cell Classification 12454.

Specifications:

Pressure ratings are for water service at 73°F. Derate for elevated temperatures and aggressive chemical service per manufacturer guidelines.

Industries & Applications:

The 829-249 Schedule 80 reducing slip coupling serves a broad range of industrial and commercial applications where a reliable, chemically inert 2" to 1" transition is needed:

• Industrial Process Piping — Stepping down from 2-inch distribution mains to 1-inch service branches on chemical feed, reagent delivery, and recirculation loops
• Chemical Processing & Water Treatment — Chlorination, acid dosing, and polymer injection systems where solvent-welded PVC joints outperform threaded connections in corrosive service
• Municipal & Commercial Plumbing — Transition fittings on utility water systems, pump discharge headers, and mechanical room piping where Schedule 80 strength is specified
• Agricultural Irrigation — Reducing headers on drip and micro-irrigation systems transitioning from 2-inch supply mains to 1-inch zone laterals
• HVAC & Chilled Water Systems — Non-metallic reducing connections on chemical treatment loops and condenser water piping where corrosion resistance extends service life
• Semiconductor & Electronics Manufacturing — Ultra-pure water and chemical distribution lines requiring smooth-bore, non-reactive fittings
• Aquaculture & Aquatics — Recirculating aquaculture system (RAS) plumbing and commercial pool/spa equipment rooms where chemical exposure is continuous
