Elbow, 22-1/2 Degree, Slip x Slip PVC Schedule 40 1-1/2" (465-015)

This 1-1/2" Schedule 40 PVC 22-1/2 Degree Elbow (Slip x Slip) provides the shallowest standard directional offset available in the Schedule 40 PVC socket elbow family, redirecting a 1-1/2" socket pipe run by 22-1/2 degrees from its original axis while maintaining full-diameter flow capacity through both socket ends. Constructed in white Schedule 40 PVC, it offers reliable performance in irrigation, commercial plumbing, and light industrial applications where a very slight course correction, shallow grade adjustment, or minimal angular offset is required along an all-socket pipe run — a deflection too subtle for a 45-degree elbow and far too gradual for a 90-degree turn.

Both slip socket ends accept 1-1/2" PVC pipe for permanent solvent-cement bonds, redirecting the pipe run 22-1/2 degrees between the inlet and outlet socket axes. This shallow deflection makes the 465 series the correct choice wherever a pipe run must make a slight course correction around a shallow grade change, a minor structural obstruction, or a gradual routing transition that a 45-degree elbow would over-correct — producing a nearly straight pipe run with a barely perceptible angular shift that preserves the overall routing direction of the assembly. When used in multiples, 22-1/2 degree elbows can approximate a gradual curve across a longer run length, distributing the total directional change across multiple shallow deflection points rather than concentrating it in one or two more aggressive elbow joints — a technique used in irrigation mainline routing and drain line installations where gradual sweeping transitions are preferred for both flow performance and long-term joint integrity. At 1-1/2", this elbow is most commonly specified in residential and light commercial irrigation mainline assemblies, light commercial drain and waste line offset sections, and commercial plumbing distribution runs where slight angular corrections maintain system alignment without disrupting the overall pipe routing direction.

Rated to approximately 330 psi at 73°F, this elbow is suited for standard commercial and light industrial pressure service. Its PVC composition provides excellent resistance to corrosion, scale, chlorinated water, and a broad range of chemical exposures, making it a reliable long-term alternative to metal fittings in moisture-prone or chemically active environments. NSF/ANSI 61 listing confirms suitability for potable water contact.

Apply solvent cement to both the pipe end and fitting socket at each port per ASTM D2564 procedures, using a primer appropriate for the pipe and fitting schedule. Insert pipe fully into each socket and maintain a quarter-turn during assembly for even cement distribution. Because the 22-1/2 degree offset is visually subtle, mark the intended pipe run direction on the pipe ends and fitting before cementing to ensure the correct angular orientation is achieved — the shallow deflection can be difficult to judge by eye, and an incorrectly oriented joint at this angle may not be immediately apparent until the downstream pipe run fails to reach its intended endpoint. Allow adequate cure time before pressurizing the system, and derate pressure ratings for elevated temperatures per published derating curves.

Industries & Applications:

• Irrigation & Water Distribution — Provides shallow 22-1/2 degree course corrections along 1-1/2" PVC socket mainline distribution runs in residential and light commercial irrigation systems where minor grade changes, shallow terrain undulations, and slight routing adjustments require a minimal angular deflection that a 45-degree elbow would over-correct — allowing the mainline to follow natural grade contours while maintaining near-straight routing alignment throughout the system
• Commercial Plumbing — Corrects slight pipe run misalignments, routes around shallow structural elements, and adjusts distribution header directions by a minimal 22-1/2 degrees in 1-1/2" socket PVC commercial building water supply systems where the pipe run must remain nearly straight while accommodating a slight angular deviation at the correction point
• Drain, Waste & Vent Applications — Used for shallow offset corrections on 1-1/2" drain and waste line routing sections in commercial and residential DWV systems where a gentle angular deflection is preferred over a sharper elbow at drainage direction change points to maintain adequate slope and minimize flow restrictions through the drain assembly
• Industrial Process Piping — Provides minimal directional corrections along 1-1/2" process water distribution headers, equipment feed approaches, and service line routing in water treatment, chemical processing, and manufacturing facilities where all-socket Schedule 40 PVC construction is maintained and a very slight course correction is required along an otherwise straight pipe run
• Water Treatment & Aquaculture — Used for gentle routing corrections on recirculating system distribution headers, filter feed pipe runs, and tank supply line routing where a 1-1/2" socket pipe run must accommodate a shallow grade change or minor structural deviation with NSF/ANSI 61 compliance required throughout the all-socket assembly
• HVAC & Mechanical Systems — Provides minimal angular corrections along 1-1/2" cooling tower supply lines, chilled water distribution runs, and chemically treated water system pipe routing within the Schedule 40 pressure class where very slight directional adjustments along near-straight pipe runs are required to maintain alignment with equipment connection points or structural panel layouts
