Reducer Bushing, Spigot x Slip PVC Schedule 40 2" x 3/4" (437-248)

This 2" × 3/4" Schedule 40 PVC Bushing provides a four-step, all-solvent-cement size reduction from a 2" slip socket position directly to a 3/4" PVC pipe run in a fully solvent-welded Schedule 40 system. The 2" spigot end inserts into any standard 2" female slip socket fitting or coupling for solvent cement joining on the upstream side, while the 3/4" slip socket on the outlet end accepts standard 3/4" PVC pipe for solvent cement joining on the downstream side. Both connections are permanent, chemically fused solvent-cemented joints — no threaded interface is introduced at either end of the fitting.

The four-step reduction from 2" to 3/4" spans a significant size differential — from one of the most common primary distribution pipe sizes in residential and commercial Schedule 40 systems directly to one of the most common secondary supply and equipment connection pipe sizes. Achieving this transition without the 437-248 would require a sequence of reducing couplings, stepped bushings, or multiple adapter fittings installed in series — each adding a joint, a potential leak point, and axial length to the assembly at the size transition position. The 437-248 accomplishes the complete four-step all-cement transition at the 2" socket face in a single compact bushing body, installed directly in the socket of the upstream fitting without any intermediate fittings between the 2" socket and the 3/4" outlet.

The 2" inlet establishes the primary application context for the 437-248. Two-inch Schedule 40 PVC pipe is a standard primary distribution size across commercial irrigation mainlines and submains, pool and spa primary recirculation headers, commercial plumbing distribution mains, water treatment process headers, and pump station outlet distribution piping. At every tee, cross, wye, and manifold at the 2" pipe size, spare and unused socket ports are a routine feature of system layouts designed for future expansion or current distribution. The 437-248 bridges the full span between these 2" primary distribution sockets and the 3/4" secondary supply, zone supply, and equipment connection pipe runs that draw from them — accomplishing the four-step size transition at the socket face in a single fitting.

The 3/4" outlet provides the broadest downstream application reach of any deeply reduced bushing in the 437-series 2" inlet sub-run. Three-quarter inch PVC pipe serves zone supply laterals, secondary distribution branches, equipment feed connections, chemical injection supply lines, pressure gauge supply branches, and control valve supply runs throughout residential and commercial Schedule 40 systems — the broadest secondary supply pipe size in the standard Schedule 40 distribution hierarchy. Wherever a 2" socket position must supply any of these 3/4" downstream applications, the 437-248 provides the most direct all-cement single-fitting connection.

The 437-248 should be distinguished from any 438-series Spigot × FPT equivalent at 2" × 3/4" (if stocked). The 437-248 produces a 3/4" slip socket outlet — the downstream connection is a cemented 3/4" PVC pipe run. If the downstream connection is a 3/4" male-threaded valve, solenoid valve body, or threaded component rather than a cemented pipe run, the 438-series equivalent applies. The upstream spigot end is identical for both — the downstream connection type (cemented pipe vs. threaded component) is the sole selection criterion between them.

The all-cement construction of the 437-248 preserves the monolithic, fully solvent-welded integrity of the Schedule 40 system through the four-step size reduction. Both the 2" upstream joint and the 3/4" downstream joint are permanent, chemically fused connections — the bushing becomes an integral part of the piping system at both ends, introducing no threaded interfaces or potential leak points at the size transition position.

Manufactured in white Schedule 40 PVC, this bushing delivers reliable performance across commercial, light industrial, and residential large-bore-to-secondary-supply transition applications. PVC's resistance to acids, bases, salts, chlorine, and common process fluids provides long service life where metal bushings would corrode or introduce contamination at the size transition point. NSF/ANSI 61 and NSF/ANSI 14 listings confirm suitability for potable water contact.

Rated to 280 psi at 73°F (governed by the 2" spigot end), this bushing handles standard pressure service across irrigation, commercial plumbing, pool and spa, water treatment, and light industrial applications. Two separate solvent-cemented joints must be made at installation — the spigot end into the receiving 2" socket, and the 3/4" downstream pipe into the bushing's outlet slip socket. For both joints, clean and dry all mating surfaces before application. Apply purple PVC primer to the spigot exterior and receiving socket interior for the upstream joint; apply primer to the 3/4" pipe end and the bushing's outlet socket interior for the downstream joint. At 2", use medium-body PVC solvent cement on the spigot end; standard-body cement is appropriate for the 3/4" outlet socket joint. Apply a uniform coat to both mating surfaces at each joint before inserting. Hold each joint with a slight quarter-turn twist for 30 seconds. Make the upstream spigot joint first to seat the bushing securely in the receiving 2" socket before making the downstream pipe joint at the 3/4" outlet. 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:

• Large-Bore-to-Secondary-Supply Transitions in Irrigation — The defining application for the 2" × 3/4" all-cement bushing: reduces a 2" slip socket position on an irrigation mainline tee, cross, wye, or manifold fitting directly to a 3/4" solvent-welded secondary branch or zone supply run — accomplishing the four-step size transition at the socket face in a single fitting without intermediate reducing couplings or adapter assemblies at the branch takeoff position in residential, commercial, golf course, and agricultural irrigation systems
• Commercial & Residential Irrigation Distribution — Transitions a 2" Schedule 40 PVC mainline socket position on a tee or cross to a 3/4" cemented zone supply lateral or secondary distribution branch in residential and commercial irrigation systems where the 2" primary mainline must supply 3/4" secondary zone runs through socket positions on tee branch outlets, cross ports, and manifold fittings
