SpiroFlex gasket O75 set of 10, EPDM sealing ring for Ø75 duct or pipe

SpiroFlex gasket O75 set of 10, EPDM sealing ring for Ø75 duct or pipe is a pack of ten elastic EPDM rings designed to provide a reliable seal for circular Ø75 ventilation ducts and piping. Each gasket fits into the mating surfaces of duct connectors or pipe joints, compensating for minor dimensional tolerances and reducing air leakage. The material properties of EPDM deliver resistance to weathering, ozone and moderate temperature variations, making these seals suitable for HVAC assemblies and repair work where a flexible, durable joint is required.

Advantages

These EPDM sealing rings offer elastic sealing performance that accommodates small misalignments and vibration without cracking. The set of 10 ensures a supply of consistent, preformed gaskets for multiple joints or spare parts inventory. EPDM material provides good resistance to ozone, UV aging and many common atmospheric conditions encountered in ventilation systems, contributing to long-term tightness and reduced maintenance needs.

Suitable for

• Sealing Ø75 circular ventilation ducts and pipe connections
• HVAC installations and ductwork repairs
• Replacement gaskets for fittings, couplers and joints
• Applications requiring vibration accommodation and tight air seals

Key specifications

• Material: EPDM (ethylene propylene diene monomer rubber)
• Quantity: 10 pieces per set
• Nominal diameter: designed for Ø75 ducts/pipes
• Function: elastic sealing ring for circular joints
• Resistance: weathering and ozone resistance, suitable for typical HVAC temperature ranges

How to use

Inspect mating duct or pipe ends to ensure surfaces are clean and free of sharp debris. Fit a gasket into the groove or over the spigot of the Ø75 connector, aligning it evenly around the circumference. Join the two duct or pipe ends, pressing until the gasket seats fully and the connection reaches the intended engagement depth. For assemblies with clamps or couplers, fasten according to the fitting instructions to compress the EPDM ring and achieve an airtight joint. Replace gaskets showing visible wear, hardening or damage.

Usage recommendations

Store gaskets in a cool, dry place away from direct sunlight and ozone sources to preserve EPDM elasticity. Avoid contact with incompatible chemicals such as strong acids, solvents or oils that may degrade EPDM. When used in outdoor or exposed installations, check seals periodically and replace if elasticity is reduced or cracking appears.
