Elbow, 45 Degree, Slip x Slip PVC Schedule 40 1-1/2" (417-015)

This 1-1/2" Schedule 40 PVC 45 Degree Elbow provides a permanent, solvent-cemented 45° directional change in a Schedule 40 PVC pressure piping system, routing a 1-1/2" pipe run through a half-right-angle turn in a single fitting. Both slip socket ends accept standard 1-1/2" 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 417-015 belongs in a system layout. The first is turn angle. The 417-015 produces a 45° half-right-angle turn — the standard 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, the 417-015 is the correct selection.

The second distinction is connection type. The 417-015 is a standard Slip × Slip 45° elbow — both ends are female slip sockets that accept plain PVC pipe ends for solvent cement joining; the fitting requires a section of PVC pipe on both sides of the elbow. This distinguishes it from the 423-015 (Spigot × Slip 45° Street Elbow, previously written), which has a male spigot end that inserts directly into the female socket of an adjacent fitting without requiring a pipe section at the inlet. When both connections at the 45° directional change are plain pipe ends in a fully solvent-welded system, the 417-015 is the correct selection. When the inlet connection must be made directly at the face of an adjacent fitting's socket without an intermediate pipe stub, the 423-015 street elbow applies. Both are all-cement 45° elbows at the same 1-1/2" size — the upstream connection type is the sole selection criterion between them.

At 1-1/2", the 417-015 serves a pipe size that occupies a well-defined position in commercial and residential Schedule 40 systems — the same transitional positioning established across multiple 1-1/2" entries in this catalog. The 1-1/2" pipe size appears at secondary distribution headers, pump suction lines, equipment feed connections, primary branch supply mains, pool and spa return lines, and irrigation submain laterals throughout residential, commercial, and light industrial installations. At each of these 1-1/2" pipe run positions where a 45° directional change is required, the 417-015 provides that angular transition as a permanent, all-socket solvent-cemented fitting.

The 45° geometry serves several distinct routing scenarios at this pipe size. In diagonal buried mainline routing — where irrigation submains and primary water supply lines follow property boundaries, landscape features, or structural footprints at angles other than 90° — the 45° elbow is the correct directional fitting. In approach piping to pump suction inlets where gradual angular transitions reduce turbulence and improve pump inlet hydraulics, two 45° elbows in sequence provide a smoother approach than a single 90° elbow. In compound-angle assemblies where two 417-015 fittings work together to create a lateral offset between the inlet and outlet centerlines of a pipe run — achieving a 90° routing change with displacement that a single 90° elbow cannot provide — the 45° elbow is the only standard slip fitting that enables this configuration.

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, commercial plumbing, pool and spa, water treatment, and light industrial applications at 1-1/2". 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 to prevent pushback. 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:

• Irrigation & Agriculture — Routes 1-1/2" Schedule 40 PVC solvent-welded submain and primary lateral pipe runs through 45° directional changes at field boundary diagonal alignments, property line offsets, buried mainline diagonal routing segments, and pump station approach piping in commercial, golf course, and agricultural irrigation systems where the 45° geometry suits the field geometry or approach piping requirements better than a 90° turn at the directional change point
• Pump Suction Approach Piping — Provides gradual 45° angular transitions on 1-1/2" Schedule 40 PVC pump suction approach piping in irrigation pump stations, pool pump connections, and commercial mechanical pump installations where smooth directional transitions approaching the pump suction inlet reduce turbulence and improve pump inlet hydraulic conditions relative to abrupt 90° directional changes in the suction approach run
• Pool, Spa & Aquaculture — Routes 1-1/2" Schedule 40 PVC recirculation, return, and equipment supply runs through 45° directional changes at equipment pad layout offsets, underground pipe approach transitions, structural clearances, and above-grade routing changes in commercial and residential pool, spa, and aquatic facility installations where the 45° geometry provides the correct angular offset for the spatial routing requirements
• Commercial Plumbing — Routes 1-1/2" Schedule 40 PVC branch supply mains, equipment feed connections, and secondary distribution runs through 45° directional changes at wall entry offsets, structural clearances, diagonal routing transitions, and equipment footprint approaches in commercial building mechanical systems and utility systems where the 45° geometry provides a shallower directional transition than a 90° elbow at key layout change points
• Compound-Angle Offset Routing — Used in pairs to create a lateral offset in a 1-1/2" Schedule 40 solvent-welded system — two 417-015 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 an obstruction or align with a connection point that a single 90° elbow cannot reach in the available layout space
• Water & Wastewater Treatment — Routes 1-1/2" Schedule 40 PVC process and secondary distribution piping through 45° directional transitions at structural clearances, equipment footprint offsets, and diagonal routing segments in water treatment facility process piping where the 45° angular geometry serves the spatial routing constraints at the direction change point
• HVAC & Mechanical Systems — Routes 1-1/2" Schedule 40 PVC cooling tower makeup lines, treated water distribution branches, and condensate drain piping through 45° directional changes at structural offsets, equipment clearances, and diagonal routing transitions in commercial mechanical system piping where the 45° geometry provides the correct angular offset within the solvent-welded Schedule 40 system layout
