Straight, secure connections are critical in high-flow pool plumbing, where even minor alignment or joint issues can impact circulation and system reliability. The American Granby Schedule 40 2” PVC Coupling (Slip x Slip) is a professional-grade fitting designed to permanently join two sections of 2” PVC pipe into a single, continuous run with a strong solvent-weld bond.

This coupling is commonly used in pool and spa plumbing systems for repairs, extensions, and new installations involving 2” pipe. It is frequently found on main circulation lines, pump suction and discharge plumbing, return manifolds, and equipment pad layouts. Manufactured specifically for pool environments, it provides consistent fit, proper pressure handling, and long-term resistance to pool chemicals and outdoor exposure.

This is not a general plumbing coupling—it is built for real-world pool circulation systems.

Why 2” PVC Couplings Matter in Pool Plumbing

Two-inch PVC is typically used in higher-flow sections of a pool system. Any weakness at a joint can lead to leaks, flow loss, or premature failure under constant pressure.

The American Granby 2” PVC coupling is used to:

• Join two straight sections of 2” PVC pipe

• Repair cracked, cut, or damaged circulation lines

• Extend existing suction or return runs

• Maintain proper alignment on equipment pads

Using a true Schedule 40 coupling ensures uniform internal diameter and dependable long-term performance.

Slip x Slip Connections for Permanent Installations

This fitting features Slip x Slip (socket x socket) connections, allowing both pipe ends to be solvent-welded directly into the coupling.

Slip connections provide:

• Strong, permanent joints

• Smooth internal flow continuity

• Reliable, leak-resistant performance when installed correctly

Once cemented, the coupling becomes a fixed part of the plumbing system, suitable for both exposed equipment pads and underground installations.

Schedule 40 PVC Built for Pool & Spa Systems

Manufactured from rigid Schedule 40 PVC, this coupling is pressure-rated for residential and light commercial pool systems. It is fully compatible with standard 2” Schedule 40 PVC pipe used throughout pool plumbing.

The material resists:

• Chlorinated and chemically treated water

• Temperature fluctuations

• Cracking and deformation under pressure

• Long-term outdoor and underground exposure

This ensures dependable performance throughout the life of the pool system.

Common Pool & Spa Applications

The American Granby SCH 40 2” PVC Coupling is commonly used for:

• Main pool circulation plumbing

• Pump suction and discharge lines

• Filter, heater, and chlorinator connections

• Equipment pad layouts

• Underground plumbing repairs

• New pool construction and replumbing projects

Anywhere two straight sections of 2” pool plumbing must be securely joined, this coupling is the correct solution.
