Description

Westlake Pipe & Fittings 420020 2″ SKT Cross

The Westlake Pipe & Fittings 420020 2″ SKT (Socket) Cross is a precision-engineered PVC cross-type pipe fitting designed to serve as a four-way junction in fluid conveyance systems. It is manufactured by Westlake Pipe & Fittings, a recognized brand in PVC piping and fittings that evolved from LASCO fittings and operates extensive production and distribution facilities across North America, supplying durable plastic pipe components for plumbing, irrigation, industrial, agricultural, municipal, and pool & spa applications.

At its core, the 420020 cross fitting is constructed from rigid, Schedule 40 Polyvinyl Chloride (PVC) — a thermoplastic polymer that offers excellent strength-to-weight ratio, chemical resistance, and long-term performance in environments with exposure to water, chemicals, and moisture. PVC’s inherent properties make it one of the most widely used materials in modern piping systems due to its corrosion resistance, non-toxic nature, and ease of joining with solvent-cement techniques. Standard Schedule 40 PVC fittings conform to the dimensional and performance requirements that ensure compatibility with PVC pipes of the same schedule and size.

The 2″ SKT Cross fitting features four socket-type ends, each designed to accept a 2-inch nominal Schedule 40 PVC pipe through solvent welding. The socket, or “skirted,” design allows for a snug fit where the inserted pipe is bonded inside the socket using PVC primer and cement to create a permanent, leak-resistant connection. The four outlets are laid out in a cruciform geometry — one inlet feeding three additional outlets, or vice versa — enabling fluid to branch out into four directions from a single center point. This makes the cross exceptionally useful in manifold arrangements and complex distribution networks where multiple flow paths originate from a common junction point.

Mechanically, the 420020 fitting is molded as a single, monolithic component, ensuring a seamless transition between all four sockets. The PVC material is molded to precise tolerances so that each socket end maintains the proper internal and external diameters to fit nominal 2″ pipe while delivering consistent wall thickness and strength throughout the body. The exterior of the fitting is typically smooth and free of excessive flash or irregularities, contributing to a clean, easy-to-handle piece that is straightforward to install in both open and enclosed piping spaces.

When installed correctly with solvent welding, the fitting provides a robust joint capable of handling typical working pressures associated with 2″ Schedule 40 PVC systems. One vendor list notes a pressure rating of approximately 280 psi and a temperature tolerance up to around 140 °F (60 °C) in potable water applications, which is typical for Schedule 40 PVC components of this size class. These performance metrics reinforce the fitting’s suitability for cold-water plumbing, irrigation, pool circulation and return lines, wastewater effluent systems, and a variety of light industrial fluid pathways.

In practical applications, a cross fitting such as the Westlake 420020 enables a central feed line to branch into multiple supply lines without the need for additional tees and couplings. For example, in an irrigation network, the cross fitting can distribute pressurized water from a main lateral into four garden zones. In residential plumbing, it could serve as a distribution point for multiple utility spurs off a primary cold-water line. In pool & spa systems, it simplifies routing of return jets and filtration feeds by combining or splitting flows evenly through its symmetric design. The fitting’s ability to handle potable water and meet typical standards makes it versatile across many sectors.
