Lasco® Fittings Schedule 40 PVC Coupling — 1in

Lasco® Schedule 40 PVC Coupling — 1in

The Lasco® 1-inch Schedule 40 PVC Coupling provides a straight-run connection for joining two sections of 1-inch PVC pipe in cold water irrigation, hydroponic supply, and greenhouse plumbing systems. With slip-socket ends designed for solvent-cement bonding, it creates a permanent, pressure-rated joint that resists fertilizer salts, pH adjusters, and common sanitizing chemicals without corrosion or degradation.

Key Features & Benefits

• Schedule 40 PVC Construction — Adequate pressure rating for standard cold water irrigation and hydroponic systems.
• Slip Sockets for Solvent Welding — Creates a permanent, leak-free bond with PVC pipe and standard PVC solvent cement.
• ASTM-Compliant Dimensions — Consistent OD/ID tolerances ensure compatibility with Lasco and standard Schedule 40 PVC pipe.
• Corrosion-Proof — PVC resists nutrient solutions, pH chemicals, and chlorine-based sanitizers throughout the service life of the fitting.
• Cold Water Rated — Designed for cold water service in line with typical hydroponic and irrigation operating temperatures.

Who Should Use This

Hydroponic system builders and greenhouse irrigation technicians installing or repairing 1-inch PVC supply manifolds use this coupling to join pipe runs, connect to inline components, or repair damaged pipe sections cleanly and permanently.

Compatibility

For use with 1-inch Schedule 40 PVC pipe. Solvent-weld assembly using standard PVC cement. Cold water use only. Not rated for hot water, compressed air, or pressures exceeding Schedule 40 specifications.

Frequently Asked Questions

Can I use this coupling to join Schedule 80 pipe?

Schedule 40 and 80 pipe share the same OD, so the slip socket will accept Schedule 80 pipe. Verify socket depth and PVC cement compatibility for your specific wall thickness before cementing.

Is primer required before cementing?

Many PVC cement manufacturers recommend using a PVC primer before cementing for maximum bond strength, particularly on pressure-rated assemblies. Follow the cement manufacturer's instructions.

How long should I wait after cementing before pressurizing the line?

Allow the cement to cure per the manufacturer's recommendations — typically 24 hours before full pressure testing in cold water systems at moderate temperatures.

Is this fitting safe for nutrient solution contact?

Yes. PVC is broadly chemically resistant to common hydroponic nutrient solutions and pH adjustment chemicals. Verify compatibility for concentrated or specialty additives.
