Schedule 40 PVC 45-Degree Elbow Fitting (1/8 Bend)
Make smooth, efficient directional changes in your pipeline runs with our heavy-duty Schedule 40 PVC 45-Degree Elbows. Commonly referred to in the trades as a "1/8 bend," this fitting is engineered to redirect piping pathways at a medium angle, minimizing fluid friction and static pressure drops across plumbing, drainage, and low-temperature appliance venting lines.
Featuring precision-molded slip sockets on both ends, this elbow forms a permanent chemical bond via solvent welding. It provides an airtight, leak-proof joint that is stronger than the pipeline itself.
Key Features & Benefits
-
Smooth Fluid Dynamics: The 45-degree angle offers a much gentler sweep than sharp 90-degree corners, drastically reducing turbulence and backpressure while maintaining high velocity.
-
Corrosion & Acid Immunity: 100% immune to electrochemical rusting, scaling, and pitting from aggressive household wastewater or acidic high-efficiency furnace flue condensates.
-
High-Impact Rigid Construction: Molded from premium solid-wall PVC compounds to deliver excellent tensile strength and structural crush resistance under active system stress.
-
Optimized Interior Finish: Ultra-smooth inner walls eliminate fluid and air friction, preventing the buildup of debris, sludge, or condensation within the bend.
-
Deep Socket Depth: Engineered with elongated slip sockets to maximize surface-area contact for a secure, fail-safe solvent weld.
Versatile System Applications
An essential directional fitting designed to guide pipelines across multiple critical infrastructures:
[1, 2]
-
High-Efficiency Venting: Directing exhaust and intake lines for Category IV condensing furnaces, boilers, and tankless water heaters around joists and roof slopes. [1]
-
Plumbing DWV Stacks: Offsetting vertical or horizontal drain, waste, and vent networks around structural beams, pillars, or tight framing.
-
Radon Mitigation Layouts: Routing sub-slab depressurization pipes cleanly along basement walls and through attic floors toward roof exhaust points.
-
Irrigation & Water Distribution: Directing cold-water supply lines and landscaping piping networks smoothly over uneven terrain.

Quick Solvent Weld Guide
-
Prep: Ensure the matching pipe ends are cut perfectly square and completely deburred.
-
Prime: Apply a thorough layer of purple PVC primer to the outer pipe ends and the inner sockets of the 45-degree elbow.
-
Glue: Coat both primed areas with an even layer of medium-body PVC solvent cement.
- Weld: Push the pipe firmly into the elbow socket, give it a quick quarter-turn twist to spread the cement, and hold tightly for 30 seconds until the initial bond sets.
