Description

Westlake Pipe & Fittings 420015 1.5″ SKT Cross

The Westlake Pipe & Fittings 420015 1.5″ Cross is a high-quality, rigorously engineered PVC cross-type plumbing fitting designed to provide a reliable four-way junction in Schedule 40 (SCH40) piping systems. Reserved for use where multiple branch lines must originate from a single pipe run, this fitting serves as a central nexus in diverse fluid handling applications such as residential and commercial plumbing, irrigation networks, pool and spa systems, and light industrial water distribution. Engineered for seamless integration with standard PVC pipe systems, the 420015 model stands at the intersection of robust material science, manufacturing precision, and practical jobsite performance.

At its core, this cross fitting is manufactured from premium polyvinyl chloride (PVC) — a thermoplastic polymer renowned for its strength, corrosion resistance, and long-term dimensional stability. PVC has long been the material of choice for cold-water piping applications due to its inherently smooth internal surface, chemical resilience, and immunity to rust, scaling, and many corrosive elements that degrade metal piping systems. This ensures that installations built using PVC fittings such as the 420015 exhibit reliable performance over extended service lives with minimal maintenance requirements.

Each of the four connections on this cross fitting is a 1.5-inch socket (SKT) interface, intended for solvent-weld installation with Schedule 40 PVC pipe. In solvent-weld systems, the socket end accepts the corresponding pipe, and a suitable primer and solvent cement create a permanent chemical bond between the fitting and the pipe wall. This method of assembly produces joints that are leak-proof, robust, and capable of handling typical system stresses without reliance on mechanical fasteners, threads, or gaskets. The socket design — sometimes referred to as “slip x slip x slip x slip” — simplifies alignment and insertion during installation, reducing labor time on the jobsite while enhancing overall system integrity.

What distinguishes the 420015 cross from simpler T- or elbow fittings is its four-branch configuration, offering fluid distribution in four simultaneous directions from a common intersection point. This geometry is essential in systems where you need to route water or fluid to multiple endpoints without using multiple couplings or additional fittings in sequence. In irrigation layouts, for example, it allows a main pipeline to branch off into several lateral runs toward different irrigation zones or manifolds. In pool and spa plumbing, it can serve as a central return or feed junction, simplifying complex pipe routing by consolidating connections in a single component.

While its nominal size of 1.5 inches makes it most appropriate for mid-range flow applications, it remains relevant in a wide spectrum of systems — from household water supply lines and garden irrigation loops to auxiliary piping on commercial buildings. Users value this fitting for its versatility, because across these applications, PVC materials deliver long-term corrosion resistance, maintain system cleanliness, and resist scaling that can compromise flow capacity over time.

From a manufacturing perspective, Westlake Pipe & Fittings — formerly marketed under the LASCO brand — brings decades of industry expertise to this PVC line. The company’s commitment to standards, dimensional accuracy, and tight quality control means each 420015 fitting meets consistent wall thickness, socket depth, and diameter tolerances required for reliable Schedule 40 piping. The adoption of such strict manufacturing practices reduces variability between fittings, ensures predictable solvent welding performance, and simplifies on-site assembly by matching expectations for pipe fitment and joint strength.
