45 Degree Elbow, Slip x Slip PVC Schedule 80 2" (817-020)

The 817-020 is a 2" PVC Schedule 80 45° elbow in a slip x slip configuration, providing a permanent 45-degree change of direction in a 2" solvent-weld piping run. Both ends accept standard 2" pipe or spigot-end fittings for solvent cement bonding, making installation straightforward and consistent with standard Schedule 80 PVC assembly practice.

The 45° elbow is the preferred alternative to a 90° elbow in applications where a gentler directional transition is possible — and the choice carries real hydraulic and mechanical benefits. Compared to a 90° turn, a 45° elbow produces lower head loss, reduced turbulence, and less flow velocity disruption at the change of direction. In systems where pressure drop, energy efficiency, or smooth laminar flow are design priorities, routing with 45° elbows rather than 90° turns is a straightforward way to improve system performance without increasing pipe diameter or pump capacity.

The 45° geometry is also frequently used in offset routing — a pair of 45° elbows can navigate around obstructions, transition between parallel pipe runs at different elevations, or shift a line laterally without the abrupt angular change of a 90° elbow assembly. This makes the 817-020 a practical fitting in congested mechanical spaces, around structural elements, and in any installation where the routing path requires a diagonal rather than a right-angle transition.

The all-slip design bonds both ports permanently with solvent cement, producing a clean, monolithic joint with no mechanical connections or threaded interfaces. This makes the 817-020 well-suited for buried systems, enclosed mechanical spaces, and any installation where long-term joint integrity is a priority.

Schedule 80's thicker wall construction delivers higher pressure ratings and stronger resistance to mechanical stress and chemical exposure than Schedule 40, making this elbow appropriate for demanding industrial, chemical, and process piping environments. The gray color is the standard Schedule 80 identifier, providing clear visual differentiation from white Schedule 40 components in mixed systems.

Solvent cement installation follows standard PVC practice — clean, prime, and cement both mating surfaces per ASTM D2564 procedures. Confirm the outlet orientation before cementing, as Schedule 80 socket fits leave minimal adjustment time once bonded.

Industries & Applications:

The 817-020 is well-suited for any Schedule 80 system requiring a permanent, low-turbulence 45-degree direction change in a 2" solvent-weld run:

• Industrial Processing — Gradual direction changes in 2" process piping headers, pump discharge runs, and equipment feed lines where minimizing head loss and flow turbulence at the turn is a design priority in high-flow industrial systems
• Chemical Handling — Permanent 45° transitions in acid, alkali, and reagent distribution lines where smooth flow through directional changes reduces erosion risk at the elbow and minimizes pressure drop in chemically sensitive systems
• Water & Wastewater Treatment — Low-turbulence directional transitions in treatment plant supply and distribution piping, pump station headers, and process water runs where 45° routing preserves flow efficiency compared to 90° alternatives
• Irrigation & Agriculture — Offset routing and gradual directional transitions in pressurized 2" mainline irrigation systems, including transitions around structural obstructions and elevation changes between parallel supply headers
• Commercial & Industrial Plumbing — Diagonal routing transitions in cold water supply, equipment feed lines, and mechanical room piping where 45° elbows navigate around structural elements or connect runs at non-orthogonal angles
• Aquaculture & Aquatics — Smooth directional transitions in 2" recirculating system headers, pump discharge plumbing, and filter inlet lines where maintaining flow velocity and minimizing turbulence at direction changes supports system efficiency
• Pool & Spa — Gradual directional changes in commercial pool mechanical room piping at pump discharge, filter connections, and main circulation headers where 45° routing is preferred for hydraulic efficiency
• HVAC & Cooling Systems — Low-resistance directional transitions in chilled water and process cooling distribution circuits where 45° elbows reduce head loss and pumping energy compared to 90° turns in the same run
