Dixon Valve Coupling 525 Double Bolt Clamp Plated Iron

Product Description

The DIXON VALVE COUPLING 525 is a double bolt clamp constructed from plated iron, designed to secure hose connections in industrial and commercial plumbing, fluid transfer, and general-purpose hose assembly applications. The clamp accommodates hose outside diameters ranging from 4-1/4 inches to 4-15/16 inches, making it suitable for larger-diameter hose fittings where a secure, two-bolt clamping force is required. At 0.1 pounds, the 525 is lightweight without sacrificing the clamping strength that double bolt designs are known for. Licensed plumbers, pipefitters, and industrial maintenance technicians are the primary installers of this type of clamp.

This clamp is suited for use in industrial fluid transfer lines, irrigation systems, and general hose-to-fitting connections where hose outside diameters fall within the 4-1/4 to 4-15/16 inch range. The double bolt configuration distributes clamping load evenly around the hose, reducing the risk of hose blowoff under pressure. It is commonly found in both fixed-facility maintenance and mobile equipment applications where secure hose retention is a priority.

Key Features

• Double bolt design provides even clamping pressure around large-diameter hoses
• Plated iron construction offers corrosion resistance for general-purpose use
• Fits hose outside diameters from 4-1/4 inches to 4-15/16 inches
• Lightweight at 0.1 pounds for easy handling during installation
• Sold as a single unit for flexible purchasing

Compatibility

Designed as an OEM-style replacement or direct-fit clamp for large-diameter hose assemblies requiring a double bolt clamp in the 4-1/4 to 4-15/16 inch outside diameter range.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or qualified maintenance technicians. Depressurize and drain the hose line completely before removing or installing any clamp. Tighten both bolts evenly and in alternating sequence to ensure uniform clamping force and a leak-free seal. Inspect the hose outside diameter before installation to confirm it falls within the specified range for this clamp.
