Harman Corp’s Silicone Flange Caps can be used for many purposes, especially on the job

At work, our high quality caps are great for projects where internal pressure builds up, because these caps allow pressure to escape when needed. This is possible because each cap is molded with an air vent which acts as a relief valve. They’re also used to protect threaded studs during finishing operations. Our silicone flange caps feature an oversized head along with a unique inner grip which makes application and removal easy and hassle free.

Harman Corporation’s silicone flange caps can even be used in projects where temperatures reach up to 600 degrees Fahrenheit.

Trust Harman Corporation to deliver durable, high quality silicone flange caps.
