5. Excellent chemical compatibility, polymers rarely have adverse effects with solvents.

●It swells in dimethyl sulfoxide (DMSO), dichloromethane and tetrahydrofuran (THF), and should be avoided.

PEEK blade ring used in analytical instruments

Product name: PEEK blade ring

Material: PEEK

Detailed introduction:

The blade ring is used together with the matching joint, and the two complement each other. Standard lab fitting systems work by applying external pressure (or clamping) on the outer walls of the piping system. While the nut provides the driving force for compaction, it is the blade ring that presses against the tubing, holding it in place.

In any connection system, it is impossible to use only the joint alone, because the pipe cannot be clamped, and without the transmission force of the joint, it is impossible for the blade ring to clamp the pipe wall. The fitting and blade must work together to provide a reliable and consistent support and seal on the outside of the pipe wall.

PEEK two-way, three-way, four-way, variable diameter straight-through

Product name: PEEK two-way, three-way, four-way, variable diameter straight
