Re: Resealing/Replacing Beckson Ports?
Mark Plastics, who still supply Islander and other "original" replacements, also say silicone sealant only. I can only guess that some makers spec silicone simply because it can be pulled out at a later date when it always will create new business. I've never heard an "engineering" reason to use it.
