45 Degree Elbow, Slip x Slip PVC Schedule 80 3/4" (817-007)

This 3/4" Schedule 80 PVC 45 Degree Elbow provides a permanent, solvent-cemented 45° directional change in a fully solvent-welded Schedule 80 PVC pressure piping system, routing a 3/4" pipe run through a half-right-angle turn in a single fitting. Both slip socket ends accept standard 3/4" 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 817-007 belongs in a system layout. The first is connection type. Within the Schedule 80 45° elbow family at 3/4", the 817 all-socket series serves fully solvent-welded PVC pipe systems where both sides of the 45° turn are cemented pipe ends — the correct configuration wherever the run on both sides of the directional change is plain PVC pipe joined by solvent cement. The 818-series mixed elbow bridges a solvent-welded inlet to a female-threaded outlet at the turn for connecting a threaded downstream component; the 819-series all-threaded FPT × FPT elbow (previously written at 1/2") serves fully threaded assemblies where both sides receive nipples or MPT fittings. When both connections at the 45° directional change are solvent-welded pipe, the 817-007 is the correct selection.

The second distinction is turn angle. The 817-007 produces a 45° turn — a half-right-angle directional change that serves a different set of layout requirements than the 90° turn of the 806-series Slip × Slip elbow at the same pipe size and schedule. Where a 90° elbow makes an abrupt right-angle turn at the direction change point, the 45° elbow routes the pipe run through a shallower angular offset — enabling diagonal routing around structural members, equipment footprints, and spatial constraints that prevent a right-angle turn; gradual directional transitions in congested piping layouts where the 90° geometry would create interference; compound-angle assemblies where two 45° elbows work together to create a custom lateral offset or a 90° turn with displacement between inlet and outlet centerlines; and directional changes where reducing flow turbulence and pressure drop at the turn is a design consideration. The 45° geometry is the correct selection wherever the routing requirement demands a shallower angular transition that a single 90° elbow cannot accomplish, or wherever the smoother hydraulic sweep of the 45° is specified for flow efficiency at the direction change.

At 3/4", the 817-007 serves a considerably broader application context than the 817-003 at 3/8". The 3/4" pipe size appears across secondary distribution headers, branch supply lines, chemical dosing runs, equipment feed connections, irrigation zone laterals, commercial plumbing branches, and process piping secondary runs throughout commercial and industrial Schedule 80 systems — a range of applications extending well beyond the instrument supply and gauge line niche where 3/8" PVC pipe almost exclusively operates. Wherever these 3/4" solvent-welded pipe runs must navigate a 45° directional change in a Schedule 80 system, the 817-007 is the direct solution.

The permanently solvent-cemented construction of the 817-007 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. This permanence is the correct design for the routing turns that define the fixed geometry of a piping system layout.

Manufactured in dark gray Schedule 80 PVC, this elbow delivers the increased wall thickness and mechanical strength required in industrial, chemical, and commercial pressure piping where Schedule 40 ratings are insufficient. PVC's broad chemical resistance covers acids, bases, salts, chlorine, and most common process fluids, providing long service life in corrosive environments where metal elbows would degrade or contaminate the fluid stream. NSF/ANSI 61 listing confirms suitability for potable water contact.

Rated to 690 psi at 73°F, this fitting handles standard to elevated pressure service across a wide range of fluid handling applications. 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 80 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 before cementing — the direction of the angular offset is set permanently at installation and cannot be adjusted after the 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:

• Industrial Process Piping — Routes 3/4" Schedule 80 PVC solvent-welded process lines, secondary distribution branches, and equipment supply runs through 45° directional changes at structural clearances, equipment footprint offsets, and diagonal routing transitions in chemical processing, water treatment, and manufacturing facility piping where the 45° geometry suits the spatial routing requirements better than a 90° elbow or where a shallower angular transition is specified for hydraulic efficiency
• Chemical Dosing & Distribution Systems — Provides a 45° solvent-cemented directional change on 3/4" Schedule 80 PVC chemical feed lines, reagent distribution branches, and dosing loop piping at pump outlet approach angles, structural clearance offsets, and compound-angle routing transitions in water treatment, chemical processing, and agricultural chemical handling systems where the cemented 45° elbow maintains the fully solvent-welded system construction through the angular transition
• Commercial Plumbing — Routes 3/4" Schedule 80 PVC water supply branches, equipment feed connections, and secondary distribution runs through 45° directional changes at wall entry offsets, structural clearances, and diagonal routing transitions in mechanical room and building water distribution systems where the 45° geometry provides the correct angular offset for the spatial layout requirements
• Irrigation & Agricultural Systems — Routes 3/4" Schedule 80 PVC pressure laterals, zone supply runs, and submain connections through 45° turns at field boundary offsets, equipment clearance transitions, buried mainline diagonal alignments, and above-grade routing changes in high-pressure commercial and agricultural irrigation systems where the 45° elbow provides a shallower directional change than a 90° elbow at key layout transition points
• Compound-Angle Routing — Used in pairs to create a custom lateral offset or a 90° turn with centerline displacement in 3/4" Schedule 80 solvent-welded systems — a two-elbow compound-angle configuration that achieves routing transitions not possible with a single 90° elbow in congested equipment rooms, pump station assemblies, and process piping layouts where the available routing space demands an offset rather than a direct right-angle turn
• Water & Wastewater Treatment — Redirects 3/4" Schedule 80 PVC process and secondary distribution piping at 45° routing transitions on chemical dosing lines, instrument supply branches, equipment supply runs, and zone distribution piping in municipal and industrial water treatment facilities where the 45° angular geometry suits the spatial constraints at the direction change point
• HVAC & Mechanical Systems — Routes 3/4" Schedule 80 PVC cooling tower chemical feed lines, treated water secondary distribution branches, and glycol system piping through 45° directional changes at structural corners, 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 80 system layout
