Tassello ad espansione Fischer DuoSeal 8 x 48 S PH TX A2

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
• Use in commercial and public wet areas where temporary water accumulation occurs
• Anchoring in brick, solid concrete and plasterboard (subject to substrate verification and installation instructions)

How to use

Drill a hole with the recommended 8 mm diameter to the required depth, clean the hole of dust and debris, insert the DuoSeal anchor flush with the surface and drive in the supplied screw using the appropriate PH or TX bit. Tighten the screw to expand the nylon anchor and create the watertight seal indicated by the product testing. Follow substrate-specific torque and embedment guidelines provided by the manufacturer and verify suitability for the base material before load-bearing use.

Recommendations

Observe national and local regulations for sealing and fastening in wet areas. For reliable performance in wet environments, use the DuoSeal only in combination with the supplied stainless-steel screw and follow ETAG/DIN guidance and the manufacturer’s installation instructions. For substrates not listed or where high loads are expected, consult the manufacturer’s technical documentation.
