The role of caps and plugs
The role of caps and plugs
Whether we’re talking about a fuel line, pipes, sheet metal, a hydraulic assemblies or other important parts, caps and plugs play a vital role in protection.
Often the two words are used interchangeably. Caps, however, push or thread over the outside of a part, while plugs push or thread inside the part. Whether cap or plug, here’s what they do:
Protect open holes
Caps and plugs prevent dirt, dust and any other debris from contaminating the opening during manufacturing, storage and transportation. Some caps and plugs can be used multiple times and many are versatile enough for different stages in processes.
Keep out moisture
Moisture or liquids can ruin electrical systems and cause rust. O-rings provide an airtight seal in these instances to ensure you’re offering a quality product.
Protect exposed threads
Damaged threads can bring manufacturing assemblies to a halt and stop you from getting the tightening torque you’re after. Tear-off caps not only protect your threads, but they’re quick and easy to remove.
Protect during finishing processes
When it comes to masking holes, you have a range of choices in caps and plugs for low to high-temperature processes.
Protect against damage
Scratches. Bumps. Dents. Caps and plugs are your insurance that your critical components will survive whatever happens without a blemish.

Generally – and depending on your application – you need the protection of caps and plugs during manufacturing, masking, storage and transportation, and sometimes, end uses.
