Stainless Steel Air Ducting Hose Clamp - 100mm, 150mm & 200mm Duct Clamp for Inline Fans & Carbon Filters

The Cheapest Fix for a Leaky, Smelly Grow Room

Ducting that slips off a fan or filter is the number one reason a carbon filter "stops working". Air takes the easy route out of a loose joint, the smell follows it, and your extraction drops with it. A stainless steel air ducting hose clamp locks the duct onto the flange so every cubic metre your fan pulls goes through the filter and out the exhaust, not into the tent.

Three sizes to match standard ventilation diameters: 100mm (4 inch), 150mm (6 inch) and 200mm (8 inch). Price is per clamp.

Why Stainless Steel Instead of a Cable Tie

• It holds. A worm drive clamp tightens evenly around the whole circumference, so the duct cannot creep off when the fan vibrates or the tent gets bumped.
• It does not rust. Grow rooms are humid. Corrosion resistant stainless steel keeps working season after season where zinc plated clamps and tape give up.
• It is reusable. Loosen with a screwdriver, move your fan or filter, tighten again. No cutting, no re-taping.
• It looks clean. Once installed, the clamp is nearly invisible, giving your ventilation a neat, professional finish.

What It Connects

• Plain aluminium ducting and acoustic ducting
• Inline fans and mixed flow fans
• Carbon filters and air scrubbers
• Air cooled reflectors and hoods
• Ducting splitters, reducers and tent vent flanges

Choose the Correct Size

• 100mm clamp: for 4 inch fans, filters and ducting
• 150mm clamp: for 6 inch fans, filters and ducting
• 200mm clamp: for 8 inch fans, filters and ducting

Match the clamp to the nominal diameter of your fan and ducting. If you are unsure, check the size on the product page of your fan or filter before ordering. Most setups need two clamps per run: one at the fan, one at the filter.

Fitting It Takes Under a Minute

1. Slide the clamp over the end of the ducting.
2. Push the ducting fully onto the fan, filter or reflector flange.
3. Slide the clamp back over the joint and tighten the screw with a flat screwdriver or nut driver until snug.

Frequently Asked Questions

Do I still need duct tape?
The clamp does the holding. Tape is optional for sealing pinholes or wrapping the very edge of the duct for a fully airtight, light tight finish.

Will a 100mm clamp fit 4 inch ducting?
Yes. 100mm and 4 inch are the same nominal size. The same goes for 150mm and 6 inch, and 200mm and 8 inch.

How many do I need?
One for every duct to flange connection. A basic tent with a fan and a filter usually needs two to three.
