Description
A rubber plug on a gauge is a small, conical plug that is inserted into the pressure port of a gauge to seal it off when the gauge is not in use. This helps to protect the gauge from damage and contamination.
Rubber plugs are typically made of a durable, non-reactive material such as silicone or EPDM rubber. They are available in a variety of sizes to fit different gauges.
Rubber plugs are commonly used on pressure gauges, vacuum gauges, and temperature gauges.
