Small Diameter Coupling

Features

• Built for Durable Pipe Connections: Small diameter couplings engineered specifically for plumbing and gravity-flow pipe systems with reliable performance in demanding conditions.
• Environmental Resilience: Molded synthetic rubber gasket resists degradation from ultraviolet light, ozone, biological activity, soil chemicals, and typical sewer gases while maintaining stable properties across wide temperature ranges.
• Flexible Yet Structurally Sound: Accommodates pipe movement, settlement, and minor alignment deviations without compromising the connection integrity, particularly important where ground shift or vibration occurs.
• Corrosion-Resistant Construction: All clamping hardware manufactured from high-quality stainless steel, with worm drive clamps available in both 304 and 316 grades for various environmental conditions.
• Secure Mechanical Joint: Stainless steel clamping bands apply uniform compression to the molded elastomeric gasket, forming a reliable, watertight seal that maintains its integrity over time.
• Consistent Installation Performance: Precise 60 in-lbs (≈ 6.8 N·m) torque specifications for all clamps, designed for use with standard pre-calibrated torque tools that ensure uniform compression in field installations.
• Elastomeric Gasket Sealing System: One-piece molded gasket compressed by clamp bands at each end to form water-tight, air-tight seals with axially slotted clamps that enable independent tensioning for irregular pipe surfaces.

Where Flexibility Meets Reliability.
Benefits include:

Reliable Transitions Between Pipe Materials: Creates secure, watertight seals across dissimilar materials without requiring special fittings or adapters, simplifying inventory and reducing project complexity.

Fast Installation, Even in Tough Conditions: Installs in minutes using standard torque clamps with no primer, solvent weld, or fusion needed, performing effectively even in wet, muddy, or confined trench environments.

Ideal for Low Pressure Flow Systems: Specifically designed for gravity and low-pressure pipe systems, maintaining consistent invert and preventing flow disruption that could lead to costly backups and blockages.

Absorbs Vibration and Settlement: Outperforms rigid concrete and traditional fittings in conditions with ground movement, reducing maintenance requirements and providing greater long-term peace of mind.

Field-Proven, Inspector-Approved: Meets ASTM C1173 standards for flexible transitions in gravity systems, trusted by contractors and inspectors for delivering consistent results in both residential and commercial applications.
