Silicone Hose Retention Clamp D=30mm for #150 35CC - Hatroi HA149  [HA149]

Compatibility and fit for #150 35CC setups

The Hatroi HA149 clamp is an RC silicone retention ring with a nominal 30mm diameter intended for the #150 35CC engine family named in the title. It is used to hold silicone fuel tubing in position on the hose barb or nipple fittings installed on many RC model engines.

To fit, slide the clamp onto the tubing, push the hose onto the mating fitting, then compress the clamp evenly around the connection until the tube is fully seated. Proper seating helps avoid seepage and keeps the fuel path stable for consistent engine operation.

The clamp's silicone construction gives it enough flexibility for multiple maintenance cycles while matching soft-wall tubing. If you intend to use the clamp with other engines or fittings, check outer diameter and fitting geometry to ensure a secure and compatible installation.
