This product is a closing plug used for blocking the openings of various pipelines. It is utilized in various fields to prevent the intrusion of foreign objects during plumbing work and to prevent the leakage of liquids and gases from the pipelines. Due to its simple and lightweight design, it offers excellent workability and can be quickly attached and detached as needed, greatly contributing to the reduction of labor hours. This product effectively expands the opening by sandwiching a rubber ring with a C-shaped cross-section between two inclined iron plates. 【Features】 ■ Easy operation without tools ■ Cost-effective with rubber ring replacement *For more details, please refer to the catalog or feel free to contact us.

The "VD Seal" is a self-seal with a unique single lip structure based on a U-shaped packing design. It is designed to be used over a wide range of low to high pressures by setting the angle of the lip tip, thickness, and housing structure, allowing for sealing without the lip tip being lifted or inverted. Additionally, the sealing lip has very low surface pressure against the shaft surface due to face contact, resulting in minimal wear on both the shaft and the lip. 【Features】 ■ Prevents the intrusion of external dirt, mud, and water into the sealing area of the rotating shaft ■ Used to protect bearings and retain lubricants ■ Has a unique single lip structure based on a U-shaped packing design ■ Allows for sealing without the lip tip being lifted or inverted ■ The sealing lip has very low surface pressure against the shaft surface due to face contact *For more details, please refer to the PDF document or feel free to contact us.

The "Hexaprop Seal" utilizes the advantages of U-shaped packing and is a sealing material that has the required tension against the groove. As a sealing material with a flange structure, it eliminates the hassle of attachment and detachment while providing sufficient sealing performance against vibration and expansion. The product itself adheres to the packing groove with its own tension, making it unlikely to come off easily, allowing for quick attachment and detachment of joints, which makes the work significantly easier. 【Features】 ■ Utilizes the advantages of U-shaped packing and has the required tension against the groove ■ Eliminates the hassle of attachment and detachment while providing sufficient sealing performance against vibration and expansion ■ Adheres to the packing groove with its own tension, making it unlikely to come off easily ■ Allows for quick attachment and detachment of joints, making the work significantly easier *For more details, please refer to the PDF document or feel free to contact us.
