Internal or external roofs, walls and floors on pipes and ducts of 20–300 mm diameter. When used with Tescon Vana airtight tape as the adhesive, Roflex will stick to any air or windtight membrane, smooth planed or painted timber, wood-based panel or board, concrete, metal and plastic. The end of the pipe or duct must be accessible so it can be fed through the grommet.

Roflex grommets are heat-resistant EPDM rubber seals for airtight sealing around circular pipes and ducting. For 15–320 mm diameter pipes, Roflex is available as a single pipe grommet with self-adhesive backing or a multiple pipe grommet that needs to be taped. For pipes over 30 mm and up to 320 mm diameter, Roflex can seal one pipe per grommet and is sealed with Tescon Vana airtight tape. Tescon Vana is a tape that has been tested and proved to remain airtight for 100 years. Roflex of 30 mm and larger and sold in pack sizes of 10 or 15 grommets do not come with tape. 

Features and benefits:

• Does not stick to the pipe.
• Highly adaptable.
• Easily seal around all common pipe and duct sizes.
• Stretchy EPDM rubber allows the user to easily seal around pipes and ducts with confidence in achieving a permanent airtight seal.
• The grommet allows for pipes and ducts to be re-positioned after installation without affecting the airtight seal.
• Highly versatile with multiple sizes available to seal any pipe/duct between 15–320 mm diameter.
