Cross, Slip x Slip x Slip x Slip PVC Schedule 40 2" (420-020)

This 2" Schedule 40 PVC Cross provides a four-way, solvent-cemented junction in a Schedule 40 PVC pressure piping system, with all four slip socket ends accepting standard 2" PVC pipe for solvent cement joining. The two run ports maintain the straight-through flow path of the main line, while two branch outlets exit the fitting body perpendicular to the run on directly opposite sides — creating a full four-way cross junction where a single tee would provide only one perpendicular branch.

Understanding the distinction between a cross and a tee is the essential starting point for correct product selection at a four-way junction. The tee (401-series) provides three connection points — two run ports and one branch outlet perpendicular to the run. The cross (420-series) provides four connection points — two run ports and two branch outlets perpendicular to the run on opposite sides of the fitting body simultaneously. Where a tee creates a T-shaped junction, the cross creates a ✕-shaped junction. The cross is the correct selection wherever the piping layout requires two perpendicular branch outlets at the same fitting location — one branch on each side of the main run — rather than a single branch on one side. When only one branch outlet is needed at a given point along the run, the tee is the appropriate fitting; when both sides of the run require a simultaneous branch at the same fitting position, the cross is the correct and most direct solution.

The four-way cross junction appears in specific system layouts where its geometry provides a meaningful efficiency advantage over the alternative of installing two separate tees in close proximity. In grid-pattern distribution manifolds — where a distribution header must simultaneously branch to parallel supply lines on both sides of the main run at defined spacing points — the cross accomplishes both branches at a single fitting position, reducing the number of fittings, joints, and fitting-to-fitting pipe sections required to achieve the same four-way distribution. In dual-branch irrigation systems, symmetrical equipment supply layouts, and looped distribution networks where the hydraulic design specifies simultaneous branches on opposite sides of the run, the cross eliminates the need for a second separate tee fitting downstream.

At 2", the 420-020 serves a primary distribution pipe size common across commercial irrigation submains, water treatment process headers, equipment supply mains, and facility distribution systems — a size where simultaneous dual-branch distribution at defined header positions is a recurring design requirement in grid manifold and symmetrical supply layouts. All four ends are equal 2" sockets, providing the same full 2" branch capacity at both perpendicular outlets as at the run ports, with no size reduction at any of the four connection points.

Manufactured in white Schedule 40 PVC, this cross delivers reliable performance across commercial, light industrial, and agricultural piping applications. PVC's resistance to acids, bases, salts, chlorine, and common process fluids provides long service life in environments where metal crosses would corrode or scale. NSF/ANSI 61 and NSF/ANSI 14 listings confirm suitability for potable water contact.

Rated to 280 psi at 73°F, this fitting handles standard pressure service across irrigation, water distribution, and process piping applications at 2". For installation, four separate solvent-cemented joints must be made — two at the run ports and two at the branch outlets. Work one joint at a time: clean and dry each pipe end and socket interior before application; apply purple PVC primer to both mating surfaces; apply a uniform coat of medium-body Schedule 40 PVC solvent cement to both the pipe end and socket interior; insert the pipe with a slight quarter-turn twist and hold firmly for 30 seconds. Plan the installation sequence before beginning — make the two run port joints first, then the two branch port joints, or establish the fitting position in the system before committing any branch connections; at a four-way fitting, the spatial orientation of all four branches is set permanently at the first joint and cannot be adjusted after cementing begins. Stagger the four joints and allow full cure time per the cement manufacturer's temperature and humidity guidelines before pressurizing. Apply published pressure derating factors for service temperatures above 73°F.

Industries & Applications:

• Grid Distribution Manifolds & Symmetrical Supply Systems — The defining application for PVC cross fittings: provides simultaneous branch outlets on both sides of a 2" PVC distribution run at a single fitting position in grid-pattern irrigation manifolds, symmetrical equipment supply headers, and looped distribution networks where dual opposing branches are required at defined header positions — eliminating the need for two separate tees in close proximity to achieve the same four-way junction
• Commercial Irrigation & Landscape Systems — Distributes 2" Schedule 40 PVC submain flow to bilateral zone supply branches at cross points in grid-pattern irrigation layouts, large landscape irrigation manifold systems, and commercial turf irrigation headers where the cross fitting provides simultaneous left-and-right branch takeoffs at defined spacing points along the distribution main
• Industrial Process Piping — Provides a four-way junction on 2" Schedule 40 PVC process distribution headers at cross-distribution points where parallel equipment circuits, opposing zone supply branches, or symmetrical flow distribution paths branch simultaneously on both sides of the main header in chemical processing, water treatment, and light manufacturing facility piping
• Water & Wastewater Treatment — Installs at four-way distribution junction points on 2" Schedule 40 PVC process headers, chemical distribution mains, and secondary distribution systems in municipal and industrial water treatment facilities where simultaneous bilateral branch distribution at a single fitting position is required in the process flow layout
