Durable, Long Lasting Sealing Plugs for the Ultimate Performance




Professionals across a wide spectrum depend on CSFI everyday for the protection and fortification of their mission-critical equipment. Like CSFI’s other advanced hardware, CSFI’s self sealing plugs create the ultimate seal and block against leaks in and leaks out. CSFI’s seal plugs are special groove-headed fasteners which feature a captive, built in O-ring. CSFI inserts the ring with great precision into the groove under the seal plug head, such that, when the O-ring is compressed, it forms a complete seal around the fastener. And that’s exactly how the seal plug prevents liquids and gaseses from leaking out or into your tanks and devices.

CSFI has long been the industry leader in the production of sealing products. The company crafts each seal plug with meticulous precision, using only the finest raw materials available. Seal plugs are engineered using brass and silicone rubber for the O-ring element. And not only are seal plugs highly effective, but they are also easy to use. They require minimal installation time and zero clean up time, and they can be reused for years. The seal plugs function exceptionally on a variety of surface types, provide you with metal to metal contact and grant you 360 degrees of protection.
