Flex-A-Seal Mechanical Seals:      Miscellaneous Seals

Flex-A-Pak - is injectable packing for pumps and valves with easy installation and substantially less leakage than traditional packing. It incorporates a state-of-the-art fiber and lubrication technology that requires no flush water and universal packing where seals can’t be applied. The latest chemical and fiber technology is utilized making installation easy by conforming to worn shafts with low coefficient of friction. Self-lubricating, it does not need a flush or cooling water. Since the material is long lasting, it will not dry out or harden. Easy flow fittings and injection guns are cost effective. Quick maintenance re-packs are available. With Flex-A-Pak, there is less packing drag on the shaft. It can be injected or hand packed. We offer styles to meet most industrial conditions. Flex-A-Pak eliminates leakage, lowers operating costs, reduces maintenance time, saves energy, reduces shaft and sleeve wear. Other benefits include extended equipment life, minimized heat generation, and reduced water usage.

Hermetic Bellows - Flex-A-Seal's welded metal bellows perform the most demanding of tasks from extremely toxic and corrosive, to high pressure and / or high temperature. Some of the many industries these bellows have been applied in are: petrochemical, pharmaceutical, pulp & paper, high vacuum, high speed, down hole drilling, energy, hazardous material handling, cryogenics, marine, and others.

For all of Flex-A-Seal's welded metal bellows, the TIG (Tungsten Inert Gas) welding method is utilized. This provides superior fine control of the arc which results in efficient, clean, and long-lasting welds. Flex-A-Seal has the capacity to manufacture a myriad of sizes and styles of fixtures and end fittings.
