22 1/2 Degree Elbow, Slip x Slip PVC Schedule 80 3" (865-030)

The 3" PVC Schedule 80 22-1/2 Degree Elbow (Part No. 865-030) is a pressure-rated, gray-body fitting designed to redirect a Schedule 80 PVC piping system through a shallow 22-1/2-degree change in direction. Both ports accept solvent-cement joints in a slip (socket) configuration, producing a rigid, leak-resistant assembly suited to the elevated pressures and chemically demanding environments where Schedule 80 is the specified standard.

The 22-1/2-degree deflection angle is the defining characteristic that sets this elbow apart from the more common 45-degree and 90-degree alternatives. At less than a quarter turn, the 22-1/2-degree elbow produces the gentlest standard directional change available in the PVC pressure fitting lineup — a shallow offset that redirects flow with minimal turbulence, minimal pressure drop, and the lowest flow resistance of any standard elbow configuration. This makes the 22-1/2-degree elbow the preferred specification in high-velocity systems where even the moderate energy loss of a 45-degree elbow is undesirable, in long-radius routing situations where gradual directional changes are required to follow structural geometry, and in applications where two 22-1/2-degree elbows are combined in series to produce a custom 45-degree offset with a longer overall sweep than a single 45-degree fitting would provide.

The 22-1/2-degree elbow also plays a specific practical role in system routing. Where a pipe run must navigate a minor angular deviation — such as aligning to an equipment port that is slightly off-axis, clearing a structural member with a shallow bypass, or compensating for a grade change along a buried run — the 22-1/2-degree elbow accomplishes the correction in a single fitting without the visual or hydraulic impact of a 45-degree or 90-degree turn. This is particularly relevant in exposed mechanical room installations and process piping where system geometry is visible and alignment precision matters.

At 3", this elbow serves mid-scale industrial, commercial, and municipal applications where Schedule 80 gray PVC is specified for its pressure rating and chemical resistance. The slip x slip configuration keeps the installation fully solvent-cemented throughout, maintaining the structural integrity and pressure rating of the surrounding Schedule 80 assembly without introducing threaded interfaces at the elbow joints.

Manufactured from Type I, Grade I PVC compound, this fitting conforms to ASTM D2467 dimensional standards and delivers the wall thickness and pressure ratings that define Schedule 80 over Schedule 40. Compatible with Schedule 80 PVC pipe and solvent cements conforming to ASTM D2564.

Industries & Applications:

• Industrial & Chemical Processing — Shallow directional changes on chemical-resistant pressure runs where minimizing turbulence and pressure drop at direction changes is a system design priority, or where two 22-1/2-degree elbows are combined to produce a custom 45-degree offset with a longer sweep geometry
• Municipal Water & Wastewater — Minor angular corrections and shallow offsets on 3" distribution, collection, and treatment infrastructure where the pipe run must follow grade changes, navigate structural elements, or align to off-axis equipment ports
• Commercial Plumbing — Exposed mechanical room and equipment room piping where a shallow directional change is required for alignment precision without the visual or hydraulic impact of a 45-degree or 90-degree elbow
• Irrigation — Pump station and mainline routing adjustments on pressurized 3" irrigation systems where a gentle directional change is needed to clear structural elements, follow terrain, or align to equipment connections
• Mining & Oil Field — Corrosive fluid handling systems on 3" Schedule 80 PVC infrastructure requiring a shallow-angle directional fitting with minimal flow resistance at the bend point
• Power Generation & Utilities — Cooling water and process fluid systems where 3" Schedule 80 PVC lines require a precise, low-resistance directional correction at structural offsets, equipment connection alignments, or system routing transitions
• Aquaculture & Water Treatment — Recirculating system headers and distribution mains where shallow directional changes in 3" cemented PVC runs are required to follow tank geometry, equipment positioning, or facility layout without high-resistance elbow fittings
