22 1/2 Degree Elbow, Spigot x Slip PVC Schedule 40 3" (466-030)

The 466-030 is a 3" PVC Schedule 40 22-1/2 degree elbow with a spigot (male plain end) inlet and a slip (socket) outlet, designed to produce a shallow 22-1/2 degree change of direction in a solvent-welded PVC pipeline. The spigot inlet inserts directly into any standard 3" Schedule 40 socket fitting or pipe hub and is joined with solvent cement and primer per ASTM D2564, while the slip outlet accepts a standard 3" PVC pipe end joined the same way — creating a fully solvent-welded, permanent, pressure-rated directional change with no threaded connections at either end.

Manufactured from rigid PVC compound conforming to ASTM D1784 cell classification requirements, this elbow delivers the corrosion resistance, chemical compatibility, and long service life associated with Schedule 40 PVC across a wide range of commercial, industrial, and municipal piping systems. The Schedule 40 wall thickness provides reliable pressure-rated performance for both pressurized distribution systems and gravity-flow applications.

The 22-1/2 degree bend angle is the defining characteristic of this fitting and the primary reason it is specified over a 45 or 90 degree elbow. Where larger-angle elbows produce abrupt directional changes that generate turbulence, head loss, and flow restriction at the bend, the 22-1/2 degree elbow introduces only a shallow directional offset — minimizing flow disturbance and pressure drop while allowing the pipeline to follow grade changes, route around obstacles, or align with angled structures and equipment in situations where a straight run is not geometrically possible but a full 45 or 90 degree turn would be excessive. Two 22-1/2 degree elbows in series produce a 45 degree total offset, and four produce a full 90 degree change of direction in a gradual sweeping configuration — a layout frequently used in high-flow mainline applications where minimizing head loss through the bend geometry is an engineering priority. The spigot x slip end configuration inserts directly into an existing socket fitting at the inlet, eliminating the need for an additional coupling at that connection and keeping the overall assembly compact. Both joints are permanent solvent welds, appropriate for fixed installations where the direction change is a long-term design element.

Industries & Applications:

• Irrigation & Agriculture — Shallow directional offsets in 3" pressurized mainline pipe runs navigating grade changes, berms, buried obstacles, and angled field boundaries in large-scale irrigation systems where minimizing head loss through the bend is a hydraulic design priority
• Municipal Water & Wastewater — Gradual pipeline direction changes in pump station discharge headers, treatment facility distribution piping, and water main assemblies where shallow bend angles are specified to reduce turbulence and pressure loss in high-flow 3" pipe runs
• Industrial Process Piping — Low-resistance directional offsets in chemical distribution, cooling water, and process fluid systems where pipeline routing must accommodate structural elements or equipment layouts without the flow restriction of a 45 or 90 degree elbow
• Commercial Plumbing — Navigating 3" supply and distribution pipe runs around structural columns, beams, and mechanical equipment in mechanical rooms and building service spaces where a shallow directional change is preferable to a full 45 or 90 degree turn
• Fire Suppression — Gradual direction changes in 3" fire suppression mains and branch supply headers where minimizing fitting-induced head loss is required to maintain system hydraulic performance and design flow rates at sprinkler heads
• Drainage & Site Utilities — Shallow angular transitions in 3" gravity drain and site utility piping where the pipeline must follow grade contours or route around buried infrastructure with minimal disruption to flow velocity and drainage capacity
