Avdel® Avseal® II 02961-00708 High Pressure Series Blind Sealing Plug; M7 Diameter, Aluminium Sleeve, Steel Stem Finish

Avseal® II plugs holes in thin metal components situated in restricted areas. Two-piece structural stem locking mechanism seals holes with diameters ranging from 4-20 mm in steel, iron, and aluminum. Plugs can be placed flush to the hole or deep in casting, creating a pressure-tight seal with push-out resistance up to 300 bar (4,350 psi). Applications include engine blocks, cylinder heads, transmission components, brake systems, compressors, hydraulic blocks, and pumps. The Avseal® II system delivers leak-resistant sealing in predrilled holes with width tolerances six times larger than present systems. The Avseal® II system also eliminates such preliminary processes as reaming, tapping, extra sealant, or torque-controlled tools. Other features include a zinc-plated steel mandrel crimped for ease of installation by standard hand-held tools and high-speed automation equipment. A tapered plug stem ensures ease of entry into tooling equipment.

• Fully annealed sleeve - high sealing performance
• Hole fill capacity - improved seal and wider hole tolerance
• Larger hole tolerance - simplified hole alignment when automated placing is required
• Seal by compression of the sleeve - improves sealing with great hole fill capability over a wider hole tolerance
• Internal lock - flat nose tip and ease of use
• Improved stem retention - increased vibration resistance
• No locking ring formed by nose tip - standard equipment reduces preventative maintenance
• Low force special version - can be used in thin wall applications
• Tapered sleeve and stem - ease of entry into application and nose tips, suited to automated systems
• Shorter placed length, blindside protrusion reduced - use in restricted space or thin wall
• Can be easily modified - can suit specific applications
• Ease of placing with standard tooling - the quality of the seal is not operator dependant
