I want a plug with a 3 mm inner diameter for a leak test of a container with a pipe with a 4 mm inner diameter, but I can not find it but use this plug and use a hole with an inner diameter of 3 mm.

I can not find a suggested stopper that can be used for an inner diameter of 4 mm, and we are forced to make additional work and use it. We can make it by making a mold but we do not need the quantity so far so we are doing this kind of correspondence. It will be appreciated if there is a plug with a hole that can accommodate an inner diameter of about 4 mm. Currently I am using some extra work.
I bought it for the eye of the sash part hole (10 mm), but the silicone plug is so soft that it will penetrate. It is unkind that it does not describe the adaptive size of the hole that can be used. Even though we needed four, we wereted all in 10 sets.
