Deep Socket Coupling, (2.169) Slip x Slip PVC Schedule 40 1-1/2" (482-015)

This 1-1/2" Schedule 40 PVC Deep Socket Coupling (Slip x Slip) provides an extended-engagement solvent-cement pipe joint for field repair work and high-confidence cemented connections, featuring a significantly deeper socket on each end than a standard slip coupling — with a published socket depth of 2.169" — to allow the fitting to slide fully over a cut pipe end during repair installation and to provide a substantially greater cement contact area at each joint. Constructed in white Schedule 40 PVC, it is the correct coupling specification wherever a standard-depth socket coupling cannot accommodate the pipe engagement required by the installation method or where the additional socket depth provides meaningful added joint security at a critical service location.

Both 1-1/2" slip socket ends accept 1-1/2" PVC pipe for permanent solvent-cement bonds, with each socket providing 2.169" of pipe engagement depth — substantially deeper than the socket depth of a standard 429 series slip coupling at the same nominal size. This extended depth is the defining functional feature of the 482 series, enabling two primary installation scenarios that the standard coupling cannot support: first, as a field repair coupling, the deep socket allows the fitting to be slid completely onto one existing cut pipe end (clearing the opposite cut end), aligned with the gap, and then slid back to center over both pipe ends to make up both joints — a repair installation method that is impossible with a standard coupling where the socket is too shallow to fully clear one pipe end while still engaging the other; second, at new construction joints in high-vibration, high-pressure, or critical service locations, the extended socket depth provides a proportionally larger cement bond area at each joint, increasing joint strength and long-term reliability beyond what a standard coupling provides at the same nominal size. The 482 series deep socket coupling is not a replacement for the standard 429 series slip coupling in routine new construction applications — its extended depth adds material cost and is typically reserved for the specific scenarios where the additional socket engagement is functionally required or strongly preferred.

Rated to approximately 330 psi at 73°F, this coupling is suited for standard commercial and light industrial water distribution and irrigation service within its pressure class. Its PVC composition provides excellent resistance to corrosion, scale, chlorinated water, and a broad range of chemical exposures. NSF/ANSI 61 listing confirms suitability for potable water contact.

For repair installation: slide the coupling fully onto one cut pipe end until that end bottoms out in the far socket, confirm the opposite cut pipe end is aligned, then slide the coupling back toward center until both pipe ends are equally engaged in their respective sockets. Apply solvent cement to both pipe end exteriors and fitting socket interiors per ASTM D2564 procedures before sliding; work quickly as the extended socket depth means the cement must distribute across a larger surface area before initial set. For new construction installation: apply solvent cement to both the pipe end and fitting socket at each port per ASTM D2564 procedures, inserting fully and maintaining a quarter-turn during assembly. Allow adequate cure time before pressurizing the system, and derate pressure ratings for elevated temperatures per published derating curves.

Industries & Applications:

• Irrigation & Water Distribution — Repairs damaged or severed 1-1/2" PVC socket mainline and distribution pipe sections in the field by sliding the deep socket coupling fully over one cut pipe end, centering over the gap, and cementing both joints without excavating additional pipe length — the extended 2.169" socket depth enables the slide-and-center repair installation method that a standard-depth coupling cannot accommodate at this common mainline distribution diameter
• Commercial Plumbing — Repairs 1-1/2" Schedule 40 PVC pipe sections damaged by freeze, mechanical impact, or construction activity in commercial building water distribution systems where the deep socket coupling's extended engagement depth allows field repair without complete pipe section replacement, minimizing system downtime and repair scope at pressurized supply runs throughout the building
• Industrial Process Piping — Joins 1-1/2" Schedule 40 PVC pipe sections at high-vibration, high-stress, or critical service locations in water treatment, chemical processing, and manufacturing facilities where the extended cement contact area of the deep socket coupling provides greater joint strength and long-term reliability than a standard coupling at the same nominal size — appropriate for pump discharge piping, equipment connection approaches, and any joint location subject to ongoing mechanical stress
• Chemical Handling — Repairs and joins 1-1/2" schedule 40 PVC pipe sections in chemical distribution and process piping systems conveying acids, caustics, and other aggressive fluids where the deep socket coupling's extended engagement depth provides higher joint confidence at cemented connections in chemically demanding service environments where joint failure consequences are more severe than in standard water distribution applications
• Water Treatment & Aquaculture — Used for field repair of 1-1/2" PVC pipe sections in recirculating system distribution headers, filter manifold supply lines, and tank distribution assemblies where the deep socket coupling enables in-place repair without full section replacement and NSF/ANSI 61 compliance is required throughout the repaired assembly
• HVAC & Mechanical Systems — Repairs and joins 1-1/2" Schedule 40 PVC pipe sections at mechanically stressed or vibration-exposed locations on cooling tower supply lines, chilled water distribution assemblies, and chemically treated water system piping within the Schedule 40 pressure class where the extended socket depth provides higher joint confidence than a standard coupling at locations subject to ongoing mechanical loading
