Repair Collar AGAflex OBA 4" (11010009) for Pipe Connections

AGAflex OBA 4" repair collar is a mechanical clamp designed to restore the integrity of 4-inch pipelines. Intended for use on damaged or leaking sections, the collar creates a sealed connection around the pipe to contain leaks and support the pipe structure. The design suits plumbing, HVAC and industrial piping systems where a compact, on-site repair method is required.

Advantages

The repair collar provides a straightforward mechanical seal without the need for extensive disassembly of the pipeline. Its construction enables rapid installation and minimizes operational downtime. The collar is compatible with standard 4-inch pipe dimensions and offers a reliable containment for common leak types, reducing the need for immediate pipe replacement.

Suitable for

• Temporary or permanent repairs of 4-inch water and waste pipelines
• On-site leak containment in HVAC systems
• Industrial process pipes requiring quick mechanical sealing
• Plumbing maintenance where access is limited and fast repair is needed

Key specifications

• Pipe nominal diameter: 4 inches
• Function: mechanical repair collar / pipe clamp for leak sealing
• Application areas: plumbing, HVAC, industrial piping
• Installation: external clamp around damaged pipe section for sealing and support

How to use

Position the repair collar around the damaged section of the 4-inch pipe ensuring the sealing surface aligns with the leak. Tighten the clamp screws evenly according to the manufacturer's recommended torque sequence to compress the sealing element and form a leak-tight mechanical joint. Verify the seal under normal operating pressure and, if necessary, retighten bolts incrementally. The collar can remain in place as a temporary or long-term solution depending on system requirements and inspection results.

Usage recommendations

Prior to installation, clean the pipe surface of loose debris, corrosion and fluids to ensure full contact with the sealing element. Confirm material compatibility with conveyed media and operating temperature/pressure. Where the pipe wall is severely corroded or structurally compromised, assess the need for a comprehensive repair or replacement rather than relying solely on a clamp.
