The K-Connect system consists of a bushing, a split-grooved clamping ring, and a polymer sealing. The split-grooved clamping ring and polymer sealing are slipped over the capillary "back to back", while the bushing tightens all parts.
K-Connect fingertight fittings can optionally be tightened further using wrenches if a higher backpressure resistance is needed.

The DYNASEAL connecting system connects capillaries made out of stainless steel and PEEK, as well as PTFE and Tefzel tubings with low dead volumes. It allows maintenance-free operation and provides a long life. Suitable for UNF-threads of type 10/32.
The system consists of a bushing, a split-grooved clamping ring (3), and a polymer sealing (4). The split-grooved clamping ring and polymer sealing are slipped over the capillary (2) "back to back", while the bushing (1) tightens all parts when installed to the connecting part (5) and pushed gently to the stop position in connecting part (6). Thus, leak-free operation is made possible.
DYNASEAL connections are pressure stable up to 450 bar.
DYNASEAL can be optionally used with double-cone sealings made out of PEEK. In this case, pressure stability is accordingly reduced to 150 bar.
DYNASEAL is adaptable in new conditions such as variable bore depths or detector connections because it is mobile and reusable.

The DYNASEAL connecting system connects capillaries made out of stainless steel and PEEK, as well as PTFE and Tefzel tubings with low dead volumes. It allows maintenance-free operation and provides a long life. Suitable for M8x1 threads.
The system consists of a bushing, a split-grooved clamping ring (3), and a polymer sealing (4). The split-grooved clamping ring and polymer sealing are slipped over the capillary (2) "back to back", while the bushing (1) tightens all parts when installed to the connecting part (5) and pushed gently to the stop position in connecting part (6). Thus, leak-free operation is made possible. DYNASEAL can optionally be used with biconical sealing rings.
