American Granby SCH 40 PVC Coupling Slip x Slip 1"

Straight, reliable pipe connections are foundational to every properly built pool plumbing system. The American Granby Schedule 40 1” PVC Coupling (Slip x Slip) is a professional-grade fitting designed to join two sections of 1” PVC pipe into a single, continuous run with a strong, permanent solvent-weld connection.

This coupling is commonly used in pool and spa plumbing systems for repairs, line extensions, and equipment connections where 1” plumbing is specified. It is frequently found on chemical feed lines, booster pump plumbing, heater bypass circuits, automation systems, and auxiliary circulation lines. Manufactured specifically for pool environments, it delivers consistent fit, pressure reliability, and long-term resistance to pool chemicals and outdoor exposure.

This is not a general hardware-store fitting—it is built for real pool plumbing conditions.

Why 1” PVC Couplings Matter in Pool Plumbing

One-inch PVC plumbing is often used in critical support roles within a pool system. A poorly manufactured coupling can cause leaks, misalignment, or premature failure, especially under constant chemical exposure.

The American Granby 1” PVC coupling is used to:

• Join two straight sections of 1” PVC pipe

• Repair cracked or cut plumbing lines

• Extend existing pipe runs

• Maintain proper alignment on equipment pads

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

Slip x Slip Connections for Permanent Plumbing

This fitting features Slip x Slip (socket x socket) connections, allowing both ends of the pipe 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 and is suitable for both exposed 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 1” 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 1” PVC Coupling is commonly used for:

• Chemical feeder plumbing

• Booster pump and auxiliary circulation lines

• Automation and control plumbing

• Heater bypass piping

• Plumbing repairs and retrofits

• Underground pool plumbing installations

Anywhere two straight sections of 1” pool plumbing must be securely joined, this coupling is the correct solution.
