The Ubbink Air Excellent AE34C Seal Ring is an essential duct accessory used to create secure, airtight mechanical connections within the Air Excellent ventilation system. Designed specifically for AE34C ducts, these seal rings eliminate the need for messy tapes or sealants, delivering a clean, professional finish that stands the test of time.

Used in conjunction with an AE34C click ring, the seal ring ensures consistent airtightness across the system. This helps maintain low system pressure loss, reduces fan energy consumption, and keeps noise levels to a minimum — the sort of quiet efficiency good ventilation has always aimed for.

Supplied in a convenient pack of 10, these seal rings are ideal for both new installations and system modifications, ensuring reliable performance throughout the duct network.
