Fasteners - Sealing Plugs
Avseal®
Description
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 hole or deep in casting, creating 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.
Advantages
-
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, blind side protrusion reduced - use in restricted
space or thin wall
-
Can be easily modified - can suit specific applications
-
Ease of placing with standard tooling - quality of seal is not operator dependant
