Bushing, Spigot x Slip (Flush Style) PVC Schedule 80 2-1/2" x 1-1/2" (837-291)

The 837-291 is a 2-1/2" x 1-1/2" PVC Schedule 80 flush bushing in a spigot x slip configuration, designed to reduce pipe or fitting connections from a larger 2-1/2" socket down to a 1-1/2" slip outlet in a compact, flush-style profile. The spigot (male) end is sized to insert directly into a matching 2-1/2" Schedule 80 socket, while the slip (female) end accepts standard 1-1/2" pipe or a fitting for solvent cement bonding.

Schedule 80 PVC offers a thicker wall than Schedule 40, delivering higher pressure ratings and improved resistance to mechanical stress — making this bushing well-suited for industrial piping systems, chemical handling lines, and other applications where durability and long-term performance are non-negotiable. The gray color is standard for Schedule 80 PVC and provides a clear visual distinction from Schedule 40 (white) components in mixed systems.

The flush bushing design keeps the transition compact and in-line with the socket bore, making it a practical choice when space constraints or clean inline aesthetics matter. Solvent cement installation follows standard PVC practice — clean, prime, and cement both mating surfaces per ASTM D2564 procedures. For 2-1/2" joints, use of a heavy-bodied cement is recommended to ensure adequate fill across the larger spigot surface.

Industries & Applications:

The 837-291 flush bushing is used across industries that rely on PVC Schedule 80 piping for corrosion-resistant, pressure-rated fluid handling:

• Industrial Processing — Inline size reductions in process piping for chemical transfer, pH-neutral fluid conveyance, and general plant utility lines
• Chemical Handling — Reducing connections in acid and alkali distribution systems where metal fittings are unsuitable
• Water & Wastewater Treatment — Connecting differing pipe sizes in treatment plant infrastructure, pump stations, and distribution headers
• Irrigation & Agriculture — Joining mainline supply runs to smaller lateral distribution lines in agricultural and landscape systems
• Aquaculture & Aquatics — Integrating size changes in recirculating system manifolds and filter plumbing
• Commercial Plumbing — Pressure-rated reduction points in cold water supply, industrial process lines, and mechanical room piping
