Polyimide Tape Polyimide is an excellent tape material for applications with temperature extremes. It can be used in temperatures up to 500°F/260°C, and as low as -452°F/-269°C. With its high dielectric properties Polyimide Tape is widely used by the MWD industry and aerospace industries, and conforms to MIL-P-46112, TYPE I . The Silicone adhesive used on the tape ensures that it does not leave any reside behind when removed. |

Oil Housing Screens Our high flow oil-housing screen is made from a heat treated stainless steel. The material is designed to resist wash, and the hole slots are designed to increase flow through the screen. The increase in flow is accomplished through larger chamfered slots. These screens allow protection from large wellbore debris but will not pack off like standard designs where high LCM is a concern. Custom sizes available upon request. |
 | Pipe Screen Our MWD pipe screens are made from 304SS with the collars and spear points made from 17-4HT steel. The screens then go through a QPQ process, which further enhances the strength of the pipe screen. These screens are designed to resist wash in the harshest down hole environments. |
 |
Polyseals Materials stocked include Viton™, HNBR, bronze filled PTFE and Hytrel®. |
 |
Snap Rings and Spring Pins Retainer ring materials include stainless steel, carbon steel and beryllium copper. Spring pins available in various stainless steel materials. |
 | Snubber Assemblies Hi-Tech Seals offers two-piece snubber assemblies for battery, electronic and gama connections. The assembly comes with our silicone snubber shells and is a direct replacement for one-piece snubber assemblies. The use of the shells eliminates the need to have snubbers re-injected with silicone saving time and money. |
 | Specialty Rubber Parts Compensation Membranes, Snubber Inserts and Bellows. |
 | T-seals The T-seal design consists of a T-shaped elastomer component supported by a back-up ring on both sides. The combination of these elements results in a stable seal that ensures a positive sealing lip configuration. Popular materials include NBR, HNBR and FKM/Viton™ for the elastomer component and KasPex™ PEEK for the back-up rings. |
 | Wolcar™ Carbide We design and manufacture WolCar™ carbide components that exceed our customers’ application requirements and increase product longevity. Common components include one-piece bottom sleeves, poppet tips, rotors, stators, main and servo orifices. Our most common binder agents for our carbide are cobalt and nickel. We can formulate custom carbide compounds to meet your specific application demands. |
