A sealing cap is a lid that seals a hole that has been drilled for processing reasons. These caps are vital for maintaining the integrity of the hole and preventing external contaminants.
The materials used for sealing caps include rubber and metal, chosen for their excellent oil and heat resistance. For larger spaces, the cap may be embedded and secured externally with a stop ring. Ensuring airtightness and ease of removal is crucial. Designed to prevent the ingress of foreign matter and the leakage of stored lubricants, these caps boast high heat and abrasion resistance. There are various types of sealing caps, ranging from easy-to-open designs to those tailored for specific uses like closing the ends of flexible pipes.
Sealing caps are widely used across various machinery, including automobiles, construction and agricultural machinery, and machine tools. In construction, they serve to close pipe ends and safeguard flow sensors. In the electrical and electronic sectors, they protect connectors when not in use. Additionally, sealing caps find use as lids for liquid containers, such as those containing chemicals and oils, and as specialized lids for various packaging containers.
The term "cap seal" closely resembles "sealing cap" but specifically refers to a film-like seal used over bottle caps, commonly seen on wine or sake bottles. It may also denote the sealing rubber material inserted inside the cap or into the threaded part of the cap, enhancing the seal's effectiveness.
