SECRET JARDIN RUBBER DUCT COUPLING 200MM

Description

Secret Jardin Rubber Duct Coupling 200mm is a flexible rubber connector for joining 200mm ventilation components — inline fans, carbon filters, and rigid or flexible ducting — in grow tents and grow rooms, providing both an airtight seal and effective vibration isolation to reduce fan noise transmission through the duct system. We have been recommending Secret Jardin accessories to UK growers since 2017 as part of a professionally engineered grow tent ventilation setup, and the 200mm rubber coupling is the right-sized solution for the most popular medium-to-large inline fan installations.

The Noise and Performance Benefits of Rubber Duct Couplings

The difference between using a rubber coupling and a metal clamp to connect a fan to a carbon filter is immediately apparent when you place your hand on the carbon filter body during operation. With a metal clamp connection, the filter vibrates noticeably — that vibration is transmitted directly along the filter housing, through the mounting hardware, and into the tent frame and surrounding structure. With a rubber coupling providing a compliant, vibration-absorbing interface, the filter body vibrates barely at all. The practical result is a measurably quieter system without any change to the fan or filter themselves. The flexible rubber material of the Secret Jardin coupling also accommodates minor diameter mismatches and angular misalignments between components that are common in grow tent assemblies where everything has been fitted by hand — the flexibility compensates where rigid metal connectors would transmit stress to the fan or filter flanges. The 200mm size matches the 200mm Revolution, RAM, and comparable inline fans commonly used in 1.5–2.4 metre grow tent setups.

How to Install the Secret Jardin Rubber Duct Coupling 200mm

Slide the coupling over both mating flanges — fan outlet and carbon filter inlet — centring the coupling over the joint. Secure both ends with the included clamps or jubilee clips, tightening evenly for a uniform airtight seal. Check that the coupling is not pulled taut or kinked, as this would reduce its vibration isolation effectiveness. Run the system and verify that vibration transmission to the filter housing and tent frame has been reduced. Replace if the rubber shows cracking, hardening, or deterioration.

Pair the 200mm Rubber Duct Coupling with a Revolution 200 Vector EC or RAM 200mm fan, Can-Lite carbon filter, and Phonic Trap 200mm acoustic ducting for a complete, professionally assembled, low-noise extraction system. Browse our full ventilation accessories range.
