Claw Coupling Seal, NBR Rubber, Water Approved

NBR-Perbunan seals are designed for a wide temperature range. They remain flexible and tight even at typical winter temperatures below freezing.

The NBR seal is KTW-A and W-270 tested and approved for drinking water. There is no information on specific pressure limits, therefore we recommend use in the usual garden irrigation pressure range.

Yes, the seal is suitable for all claw coupling sizes and, thanks to the KTW-A and W-270 tests, is ideal for water-carrying lines, including drinking water. It also fits in older claw couplings.

Yes, it is a single seal. The stated price refers to one piece.

Yes, the material NBR Perbunan is resistant to the minerals contained in normal drinking water, such as limescale. The seal will not be affected by this.

Yes, the seal is specially designed for claw couplings in irrigation systems and is suitable for all sizes. It can therefore be used flexibly in your irrigation system.

Yes, the KTW-A and W-270 tests confirm the hygienic suitability of the material for drinking water. This ensures that the water flowing through the coupling is safe for all people, including children.

The seal is KTW-A and W-270 tested, primarily for drinking water. There are no specific approvals for sea water, so we cannot recommend this without reservation.

Yes, the seal is KTW-A and W-270 tested and therefore explicitly suitable for drinking water. It offers a safe solution for relevant applications.

The material Perbunan (NBR) is basically oil-resistant. However, since the seal is KTW-A and W-270 tested, it is primarily designed for drinking water. With constantly oily water, the certification and long-term hygienic suitability could be impaired.

Yes, the seal is made of NBR Perbunan and provides a secure seal. Since it is approved for drinking water, it is also ideal for rainwater systems.

The material Perbunan (NBR) is known for its good resistance to high temperatures, such as those that can occur in summer with direct sunlight. It reliably maintains its sealing function.

The seal made of Perbunan (NBR) is robust and designed for outdoor use in the garden. It is resistant to weather conditions such as rain and sunlight.

Yes, according to the technical data, the seal is "Suitable for: all sizes" of claw couplings. It ensures a secure and tight connection, regardless of the manufacturer of the claw coupling.

The seal is primarily tested for drinking water applications and their usual media (KTW-A, W-270). There is no resistance data available for use with specific pond filter chemicals.

NBR (Perbunan) is known for its good resistance, but is not optimally suited for permanent, direct UV exposure. Longer and intense sunlight can affect the material properties and thus the life of the seal.

The molded seal made of NBR is robust and designed for a tight connection. However, for optimal function and longevity, it is recommended to keep the contact surfaces of the claw coupling and the seal itself as clean as possible.

The seal made of Perbunan (NBR) is known for its elasticity and wear resistance. It is designed for regular use in irrigation systems and frequent coupling.

Unused seals made of NBR can retain their properties for years if stored in a dry, dark, and cool place. Make sure they are protected from direct sunlight and chemicals.

According to the technical data, the seal is suitable for all sizes of claw couplings. You can therefore use it flexibly, regardless of the specific claw coupling size.

The seal is designed for a long service life. With seasonal use, reuse the following year is generally possible, provided the seal shows no visible damage. Before use, it should always be checked for cracks or deformations.

Yes, the seal is explicitly stated as "Suitable for: all sizes" of claw couplings. It provides a reliable and secure seal for various nominal widths, including 1 to 2 inches.

Yes, according to the specification, the seal is suitable for claw couplings of all sizes. The 40mm specification in the category is a general assignment.

This seal is KTW-A and W-270 tested, which certifies its suitability for drinking water and high quality standards. This offers additional safety compared to untested seals.

Yes, the material Perbunan (NBR) is known for its elasticity and dimensional stability. As a result, the seal retains its sealing function even with frequent coupling and uncoupling.

The seal is KTW-A and W-270 tested, which certifies suitability for drinking water. There is no specific information for hot water beyond the usual drinking water temperatures.

Yes, according to the technical specifications, the seal is suitable for "all sizes" of claw couplings. You can therefore use it universally in your system.

The molded seal made of elastic NBR (Perbunan) is designed for reliable operation under varying pressure conditions. It is designed to maintain a tight seal even with fluctuating water pressure.
