## Long description

The fischer DuoSeal 8 x 48 S PH TX A2 is a two-component nylon expansion anchor that provides a watertight seal for drill holes in wet areas without the need for additional sealing compounds. Independently tested by the Testing and Certification Institute of the Säure Fliesner Vereinigung e. V., the plug with the enclosed stainless-steel screw meets ETAG 022 and DIN 18534 requirements for water exposure up to class W3-I. Designed for use in commercial, private and public wet spaces that experience splash water and temporary water accumulation, the DuoSeal is suitable where national regulations permit the use of plugs in wet areas.
Advantages
The DuoSeal combines a nylon anchor and a matched screw to form a sealed fastening that prevents water ingress into the drill hole. Certification to ETAG 022 and DIN 18534 confirms its watertight performance up to water exposure class W3-I. The included stainless-steel screw (A2) reduces corrosion risk, and the 8 mm drill diameter with 48 mm length offers a compact solution for a range of substrates. Pack quantity of 25 units supports larger installation jobs.
Suitable for
Fixing fixtures in bathrooms and showers with splash water exposure
Fastening fittings and accessories in kitchens and wet rooms
