Push-In Bore Sealing Plugs

Image of Attribute. Side1 orientation. CrossSection view. Contains Annotated. Push-In Bore Sealing Plugs .

Permanently seal unthreaded, counterbored holes in manifolds and other pneumatic or hydraulic components. These plugs resist vibration better than threaded plugs and don’t require thread sealant. They consist of a serrated sleeve with a ball bearing inside. When installed, the bearing is pushed inside the sleeve. This expands the sleeve so its serrations bite into the walls of the hole, sealing it shut.

Unlike plugs that install with an air- or hydraulic-powered tool, these plugs don’t require power to install. However, they’re harder to fit into angled or deep holes. To install, drive the installation tool (sold separately) into the plug with a hammer or arbor press.

Aluminum Sleeve—Plugs with an aluminum sleeve are ideal for plugging holes in aluminum manifolds. They resist corrosion in wet environments. These plugs are also lighter in weight than our other plugs, but they won’t handle pressures as high.

Zinc-Plated Steel Sleeve—Plugs with a steel sleeve can handle higher pressures than aluminum-sleeved plugs, but not as much as those with a stainless steel sleeve. They’re zinc plated for corrosion resistance in wet environments, but they’ll corrode from salt water and chemicals.

18-8 Stainless Steel Sleeve—Plugs with a stainless steel sleeve work in the highest pressures of any sleeve material, so they’re the best choice for hydraulic applications. They also have good corrosion resistance.

Installation Tools for Pull-Through Bore Sealing Plugs

Expand the sleeve on pull-through bore sealing plugs to permanently seal a flow path in a manifold or other channel. These tools work with the pull of a trigger, making them a good choice for high-volume assemblies. While most plugs get hammered into place, which risks damage to your equipment, these installation tools simply reach into holes to expand the plug.

Pull-Through Bore Sealing Plugs

Permanently plug unused holes–even deep or angled ones—in manifolds and other hydraulic or pneumatic components. The required installation tool reaches inside holes to expand these plugs with the pull of a trigger, making them a good choice for high-volume assembly. The tool lets you install them without risking damage to your equipment, unlike most plugs that have to be hammered in place. These plugs resist vibration better than threaded plugs and don’t require thread sealant.

They consist of a serrated sleeve with an internally threaded pin inside it. To install, you’ll need the installation tool fitted with a mandrel and nosepiece set (both sold separately). Thread your plug onto the mandrel, then position the plug within your hole. Press the tool’s trigger to pull the plug’s pin through the sleeve, expanding it. The outer serrations will bite into the hole to seal it shut. After expanding, the tool will automatically reverse its spin to pull away from the pin.

Aluminum Sleeve—Aluminum-sleeved plugs weigh less than steel-sleeved plugs, and they’re better at resisting corrosion from air and water. However, they won’t handle pressures as high as steel-sleeved plugs. They’re ideal for plugging aluminum manifolds.

Black-Oxide Steel Sleeve—Steel-sleeved plugs handle pressures more than twice as high as aluminum-sleeved plugs. This makes them a better choice for hydraulic components.
