- Product: Long Barrel Coupling (Also known as: Long Sleeve Coupling)
Headline: Secure Pipe Connections with Extended Tolerance.
Description: The Cascade Long Barrel Coupling is designed for joining pipe ends where a standard coupling length is insufficient. With an extended body length, this coupling allows for greater pipe insertion depth, ideal for bridging gaps caused by cutting errors, pipe contraction, or when replacing a section of pipe.
Key Features:
- Extended Body Length: Provides a larger sealing area and accommodates wider gaps.
- High Tolerance: Allows for pipeline expansion and contraction without breaking the seal.
- Universal Fit: Joins pipes of the same nominal bore but slightly varying outside diameters.
- Corrosion Resistant: High-grade materials with heavy-duty bolts for durability.
Galvanised Compression Couplings
Galvanised Compression Couplings are precision-cast in malleable cast iron and feature a heavy-duty, hydroformed steel body built for endurance.The prominent “centre-hex” design affords a secure grip, allowing you to tighten the end caps with ease for a perfect fit every time. A double-tapered rubber gasket provides two seals at each end, delivering exceptional leak-proof performance. Fully galvanised to guard against corrosion, these couplings are designed to last, providing a dependable connection for steel and PVC pipes.Benefits:
- Exceptional Durability: Made from heavy-duty malleable cast iron and steel for maximum strength.
- Superior Seal: A double-tapered gasket design ensures a robust, dual-seal connection at each end.
- Corrosion Resistant: Fully galvanised for long-term protection against the elements.
Ranger Coupling
Ranger Coupling is the ultimate wide-range solution, ingeniously designed to join pipes with the same nominal diameter but different outside diameters.Constructed from high-grade ductile iron and coated in protective Polyethylene (PE), these couplings offer maximum corrosion protection while preventing chipping and damage. The rubber seals are certified for use with potable water (WRAS/BS6920), ensuring safety and quality. With large-diameter, PE-coated bolts allowing for greater torque, fitting is easier and the seal is more secure than ever. The Ranger is your all-in-one solution for steel, PVC/HDPE, and asbestos pipes across a vast range of sizes.
Benefits:
- Unmatched Versatility: Connects pipes with varying outside diameters, making it perfect for transitions and complex jobs.
- Maximum Durability: Made from ductile iron and finished with a robust PE coating for the ultimate corrosion defense.
- Certified Safety: Approved for use with potable water, guaranteeing a safe and reliable connection for critical lines
Flange Adapters
The Flange Adapter is a robust wide-range coupling solution designed to join pipes with the same nominal diameter, even if they have varying outside diameters (ODs). Engineered for durability and high performance, it provides a secure connection while offering exceptional protection against environmental elements. Its specialized coating and sealing systems make it ideal for potable water applications and long-term underground use.
Key Features & Benefits
Universal Fit: Wide range couplings suitable for joining pipes with the same nominal diameter but different ODs.
Superior Durability: Body cast in high-strength Ductile Iron Grade 420/12 to BS 2789:1985 standards.
Maximum Corrosion Protection: Fully PE coated to resist corrosion and prevent chipping or gouging during handling and installation.
Potable Water Safe: Equipped with high-quality rubber seals certified to "WRAS/BS6920" standards.
Optimized Sealing: Features large diameter bolts (BS970:1991 Grade 070-M20) that are PE coated to ensure greater torque, easier fitting, and a tighter seal.
Applications
Potable water distribution networks
Pipeline connections and repairs
Water treatment facilities
Irrigation systems
General industrial fluid transfer
