45 Deg. Elbow, Slip X Slip 10" (C617-100)

The 10" PVC Class 125 45-Degree Elbow (Slip x Slip) is a large-diameter thermoplastic fitting designed for gradual directional changes in gravity-flow drainage, stormwater conveyance, and low-pressure piping systems. With slip socket connections on both ends, this fitting installs permanently via solvent cement — producing a full-bore, pressure-tight joint consistent with the inside diameter of the pipe through the bend.

Class 125 PVC fittings are dimensioned to the cast iron pipe fitting pattern, making them the correct choice when replacing cast iron fittings in existing drainage systems or when a project specification calls for cast iron pattern dimensions in a corrosion-resistant thermoplastic. This is a meaningful distinction from Schedule 40 PVC fittings, which are dimensioned differently and are not interchangeable with Class 125 in applications governed by cast iron fitting geometry. Where Schedule 40 is optimized for pressure service, Class 125 is the standard for large-diameter drainage and gravity-flow applications where the wall thickness and pressure requirements of Schedule 40 are not needed — and where the dimensional compatibility with cast iron infrastructure is an advantage.

The 45-degree bend geometry produces a shallower directional change than a 90-degree elbow, reducing turbulence, limiting pressure drop through the fitting, and easing flow transition in gravity drainage systems where maintaining velocity through bends is critical to preventing solids accumulation. At 10 inches, this fitting is typically specified in municipal drainage infrastructure, large commercial building drain systems, industrial discharge lines, and stormwater conveyance networks where large-bore PVC is the material of choice. Manufactured to ASTM D2466 standards and dimensioned to CISPI/cast iron pattern for compatibility with existing cast iron system components.

Industries & Applications:

• Municipal Drainage & Stormwater — The primary application for large-diameter Class 125 PVC; used in underground stormwater conveyance, drainage collection mains, and gravity sewer laterals where cast iron pattern dimensions are specified or where cast iron is being replaced with corrosion-resistant PVC
• Large Commercial Building Drainage — Specified in below-grade drain systems for large commercial, institutional, and industrial buildings where 10" gravity drain mains require directional transitions compliant with cast iron pattern standards
• Industrial Discharge & Process Drainage — Applied in industrial facilities requiring large-bore, chemical-resistant gravity drainage from process areas, equipment wash-down stations, and secondary containment drain systems
• Civil & Site Utilities — Incorporated in site utility plans for new construction, campus developments, and infrastructure projects where large-diameter PVC gravity drainage runs require code-compliant directional fittings
• Replacement of Cast Iron Systems — A direct retrofit option when upgrading or repairing aging cast iron drain systems; Class 125 PVC matches cast iron fitting dimensions, simplifying transitions between materials without custom adapters
• Water & Wastewater Treatment Facilities — Used in gravity drainage and effluent conveyance lines within treatment plant infrastructure where large-diameter PVC is preferred for its corrosion resistance and reduced maintenance requirements
