Frequently asked questions
- How does NS212 connect?
- Insert and twist, and the integrated lock holds the connection. Turn back to release, and both valves close as the halves separate.
- Which seal do I need?
- EPDM for water and aqueous solutions, FKM for oils and many solvents, FFKM (Simriz) for particularly aggressive chemicals. What counts is compatibility with your fluid.
- What is a PTF termination?
- A compression-style termination that holds the tubing without an extra clamp, here for tubing with 6.4 mm outer and 4.3 mm inner diameter.
