Westlake Pipe & Fittings 417020 2″ SKT 45-Degree Elbow

The Westlake Pipe & Fittings 417020 2″ SKT 45-Degree Elbow is a quintessential PVC pipe fitting engineered for reliable performance in a broad range of plumbing, water distribution, irrigation, and pool systems. Designed with both ease of installation and long-term durability in mind, this elbow fitting serves a critical role in redirecting the flow of fluids at a precise 45-degree angle within standard piping networks. Though compact in size, its design and material properties reflect careful engineering that accommodates both residential and light commercial applications.

At its core, the 417020 elbow is an elbow fitting constructed from polyvinyl chloride (PVC) — a material widely recognized across the piping industry for its strength, corrosion resistance, chemical stability, and long-term performance in aqueous environments. PVC’s proven track record makes this fitting a dependable choice for potable water systems as well as non-potable applications like irrigation and pool plumbing. The resin used meets industry standards that ensure resilience against common chemicals and environmental factors that can degrade lesser plastics over time.

The signature characteristic of a 45-degree elbow versus a standard 90-degree counterpart is the gentler change in direction it enables. This moderate angle significantly reduces turbulence and pressure loss when flowing liquids are redirected — an important factor in maintaining system efficiency, reducing stress on pumps, and minimizing noise and vibration. Such attributes make the 45-degree elbow ideal for systems where fluid flow must be carefully controlled or where piping runs must gradually change direction to accommodate architectural or mechanical constraints.

The “SKT” or socket-to-socket connection style refers to the way pipes join the fitting: both ends are slightly larger internally to allow the plain ends of PVC pipe to be fully inserted and then bonded using solvent cement. This type of connection — often called a slip socket — is widely preferred for permanent, leak-resistant joints in pressure piping systems. The solvent-welded joint creates a bond that is often stronger than the pipe itself, ensuring a robust and lasting seal when properly installed.

Because it is manufactured to Schedule 40 PVC standards, the 417020 elbow is compatible with other Schedule 40 PVC pipe and fittings. Schedule 40 refers to a specific wall thickness and pressure rating suitable for most residential and light commercial plumbing needs. In Schedule 40 fittings, wall thickness is optimized to balance strength with material economy, ensuring adequate pressure handling while remaining cost-effective. This Schedule 40 designation is consistent with common PVC piping systems used throughout North America and many other parts of the world.

Installation is straightforward for anyone familiar with PVC piping. After cutting the pipe ends square and cleaning off burrs, the user applies PVC primer and solvent cement to both the socket of the elbow and the pipe. Once inserted and seated fully, the cement cures to create a watertight and permanent bond. This simple installation process — without the need for special tools or heat fusion equipment — makes the 417020 elbow attractive for DIY homeowners and professional plumbers alike.

In terms of dimensional characteristics, the fitting accommodates a 2-inch nominal pipe size on both ends, meaning it is intended to join two lengths of 2″ PVC pipe. The actual outside diameter of a 2″ Schedule 40 PVC pipe — and thus the socket size this elbow is designed to fit — is approximately 2-11/16″. The overall length and configuration of the elbow ensure that when two pipes are joined, the centerline offset and angular change are achieved without unnecessary bulk, saving space and material.

Though a small component, the elbow is crafted to meet industry standards for quality and safety. Certifications like ASTM D2466 and NSF 14/NSF 61 (when applicable) signify compliance with recognized benchmarks for PVC fittings, including performance under pressure and safety for potable water use. These standards ensure that the fitting can handle typical working conditions — including pressure loads and temperature ranges commonly encountered in plumbing systems.
