Elbow, 45 Degree, Slip x Slip PVC Schedule 40 1-1/4" (417-012)

This 1-1/4" Schedule 40 PVC 45 Degree Elbow provides a permanent, solvent-cemented 45° directional change in a Schedule 40 PVC pressure piping system, routing a 1-1/4" pipe run through a half-right-angle turn in a single fitting. Both slip socket ends accept standard 1-1/4" PVC pipe for solvent cement joining, producing a fully cemented 45° directional change that becomes a continuous, integral part of the piping system once cured.

Two parallel distinctions define where the 417-012 belongs in a system layout. The first is turn angle. The 417-012 produces a 45° half-right-angle turn — the correct selection for diagonal routing, gradual directional transitions, compound-angle assemblies, and offset routing requirements where a full 90° turn would be geometrically incorrect or would create clearance conflicts with surrounding structure, equipment, or existing piping. The 406-series Slip × Slip 90° elbow at the same pipe size and schedule produces a full right-angle turn — correct for sharp corners, horizontal-to-vertical transitions, and standard right-angle routing changes. When the routing requirement is a shallower angular transition rather than a full right angle in a 1-1/4" solvent-welded system, the 417-012 is the direct solution.

The second distinction is connection type. The 417-012 is a standard Slip × Slip 45° elbow — both ends are female slip sockets requiring plain PVC pipe on both sides. This distinguishes it from any 423-series Spigot × Slip 45° street elbow at the same size (if stocked), which has a male spigot end that inserts directly into an adjacent fitting's socket without requiring a pipe section at the inlet. When both connections at the 45° turn are plain pipe ends in a fully solvent-welded system, the 417-012 is the correct selection.

At 1-1/4", the 417-012 serves the transitional pipe size that bridges 1" and 1-1/2" in Schedule 40 distribution hierarchies. This transitional positioning — established across multiple 1-1/4" catalog entries including the 437-250, 438-212, 401-167, 407-012, and 429-168 — places the 417-012 at pump suction approach routing transitions, strainer body approach diagonal alignments, secondary distribution header diagonal routing offsets, and equipment supply runs in commercial and residential systems where 1-1/4" pipe navigates diagonal routing requirements. The 417-012 differs from the 417-015 (1-1/2" Slip × Slip 45° elbow, previously written) in the narrower transitional-size application profile at 1-1/4" vs. the broader residential and commercial pool, spa, irrigation, and plumbing context of 1-1/2".

The 45° geometry serves several distinct routing scenarios at 1-1/4". In diagonal approach piping to pump suction inlets — where two 45° elbows in sequence produce a smoother approach than a single 90° elbow, reducing turbulence and improving pump inlet hydraulic conditions — the 417-012 provides the correct angular transition at the 1-1/4" approach pipe size. In compound-angle assemblies where two 417-012 fittings work together to create a lateral offset between the inlet and outlet centerlines of a 1-1/4" pipe run, the fitting achieves a 90° routing change with displacement that no single 90° elbow can provide. In diagonal buried or above-grade routing segments where the pipeline follows a boundary, structural feature, or equipment footprint at an angle other than 90°, the 45° elbow is the correct directional fitting.

The permanently solvent-cemented construction of the 417-012 produces a monolithic, chemically fused joint at each socket end — a connection that, once cured, is as strong as or stronger than the pipe itself and requires no periodic maintenance at the joint.

Manufactured in white Schedule 40 PVC, this elbow delivers reliable performance across residential, commercial, and light industrial piping applications. PVC's resistance to acids, bases, salts, chlorine, and common process fluids provides long service life where metal elbows would corrode or scale. NSF/ANSI 61 and NSF/ANSI 14 listings confirm suitability for potable water contact.

Rated to 280 psi at 73°F, this fitting handles standard pressure service across irrigation, pool and spa, commercial plumbing, water treatment, and light industrial applications at 1-1/4". For installation, clean and dry both pipe ends and socket interiors before application. Apply purple PVC primer to all mating surfaces — both pipe ends and both socket interiors. Apply a uniform coat of Schedule 40 PVC solvent cement to both the pipe end and socket interior at each end before joining. Insert the pipe with a slight quarter-turn twist and hold firmly for 30 seconds. Plan and confirm the 45° turn orientation and the plane of the angular transition before cementing the second joint — the direction and plane of the angular offset are set permanently at installation and cannot be adjusted after both joints are cured. Stagger the two joints where possible and allow full cure time per the cement manufacturer's temperature and humidity guidelines before pressurizing. Apply published pressure derating factors for service temperatures above 73°F.

Industries & Applications:

• Pump Suction Approach Piping — Provides gradual 45° angular transitions on 1-1/4" Schedule 40 PVC pump suction approach piping in residential and commercial pump station assemblies, irrigation pump stations, and pool and spa pump connections where smooth directional transitions approaching the pump suction inlet reduce turbulence and improve pump inlet hydraulic conditions — two 417-012 fittings in sequence producing a smoother approach than a single 90° elbow at the 1-1/4" transitional approach pipe size
• Strainer & Filter Vessel Approach Piping — Routes 1-1/4" Schedule 40 PVC strainer body approach runs and filter vessel inlet piping through 45° directional transitions at diagonal alignment corrections, structural clearance offsets, and equipment footprint approach angles in residential and commercial systems where the 1-1/4" approach pipe must navigate a diagonal angular transition to reach the strainer or filter inlet connection
• Commercial & Residential Irrigation — Routes 1-1/4" Schedule 40 PVC secondary lateral and transitional-size submain pipe runs through 45° directional changes at field boundary diagonal alignments, property line offsets, buried mainline diagonal routing segments, and pump station approach transitions in residential and commercial irrigation systems where the 1-1/4" transitional pipe serves specific hydraulic requirements between 1" and 1-1/2" and the 45° geometry suits the layout requirements
• Commercial Plumbing — Routes 1-1/4" Schedule 40 PVC secondary water supply branches, equipment feed connections, and transitional-size distribution runs through 45° directional changes at wall entry offsets, structural clearances, and diagonal routing transitions in commercial building mechanical systems where the 1-1/4" pipe navigates angular routing requirements between 1" branch supplies and 1-1/2" secondary headers
• Compound-Angle Offset Routing — Used in pairs to create a lateral offset in a 1-1/4" Schedule 40 solvent-welded system — two 417-012 elbows installed in opposing 45° orientations achieve a 90° direction change with centerline displacement between the inlet and outlet pipe runs, enabling the pipe to navigate around structural members, equipment footprints, or alignment requirements that a single 90° elbow cannot accommodate in the available layout space
• Water & Wastewater Treatment — Redirects 1-1/4" Schedule 40 PVC secondary process and distribution piping at 45° routing transitions on equipment approach runs, pump suction approach lines, strainer inlet piping, and secondary distribution diagonal routing segments in light-duty water treatment facilities where the 45° angular geometry serves the spatial routing constraints at the direction change point
• Light Industrial Process Piping — Routes 1-1/4" Schedule 40 PVC process distribution secondary headers, equipment supply approach runs, and strainer inlet piping through 45° directional changes at structural clearances, equipment footprint offsets, and diagonal routing transitions in light industrial systems where the 1-1/4" transitional pipe size serves specific process flow requirements and the 45° geometry accommodates the spatial layout
