    Pull-Through Plugs

    Image of Product. Front orientation. Contains Annotated. Protective Plugs. Pull-Through Plugs.
    Fill the entire length of through holes instead of plugging each end. Grip the small end of these plugs and pull through to mask holes during finishing. They’re also good for plugging multiple aligned holes at once.
    Chemical-Resistant EPDM—These plugs won't swell or crack when masking parts during plating, anodizing, and other chemical finishing.
    High-Temperature Silicone Rubber—Withstand multiple passes when paint baking, powder coating, and electroplating.

    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.

    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.
