25/50pcs Red VMQ Silicone O-ring CS 3.5mm Outer Diameter 18 To 27mm Food Grade Waterproof Gasket Rubber Insulated Round O-shaped Sealing Gasket

Good quality, good price, everything is great.

I ordered silicone rings 24x3.5, these are exactly what I needed, I received them, they were thinner at first glance, I measured them at home - 23.5x2.8, they are loose in the heat exchanger of the gas boiler, they don’t hold, the groove is 24x3.0. It needs to be returned.

Good material and product, well made, thank you all

Item well packaged, not tested yet.

Rings match the description
