Alfa Laval 211057 4 in Heavy Duty Tri-clamp Wing Nut 304 Ss

Product Description

The ALFA LAVAL 211057 is a 4-inch single hinge heavy duty tri-clamp fitting with a wing nut closure, constructed from 304 stainless steel. Designed for sanitary piping systems, this clamp secures tri-clamp (tri-clover style) ferrule connections by applying even clamping force around the joint. The single hinge design allows for quick assembly and disassembly without removing the clamp entirely, while the wing nut enables hand-tightening in applications where tools may not be practical. It is commonly specified by plumbers, pipefitters, and sanitary system technicians working on food processing, dairy, beverage, or industrial fluid handling installations.

This clamp is suited for 4-inch sanitary ferrule connections in both light commercial and industrial settings. The heavy duty designation indicates a reinforced band and hardware rated for more demanding service conditions compared to standard-duty tri-clamps. It is appropriate for lines carrying liquids or gases where a secure, leak-resistant mechanical joint is required and where periodic inspection or cleaning access is needed.

Key Features

• 4-inch nominal size fits standard 4-inch sanitary tri-clamp ferrules
• 304 stainless steel construction resists corrosion in wet and washdown environments
• Single hinge design allows the clamp to remain on the line during disassembly
• Wing nut closure enables hand-tightening for fast connections and releases
• Heavy duty band and hardware rated for more demanding service conditions

Compatibility

Designed as an OEM-style replacement or direct-fit component for standard 4-inch sanitary tri-clamp ferrule connections in sanitary piping systems.

Installation Notes

Installation is typically performed by licensed plumbers or pipefitters familiar with sanitary piping systems. Before servicing any line, depressurize the system and shut off fluid supply. Ensure the gasket is properly seated in the ferrule groove before closing the clamp. Do not overtighten the wing nut beyond hand-snug, as excessive force can deform the gasket or damage the ferrule.
