High pressure air packer

The use of special rubber reinforces durability under super-high pressure. Applying the air packer to two sections, one above and the other below (special purpose: contact us for more details) makes it possible to penetrate water and inject grout between them. Packer rubber is caulked with nonslip fittings uniquely developed by our company to prevents removal during the use of high pressure and allow easy replacement.
