Compression Hardware relies on the ferrule to swage or attach to the tubing to maintain the high pressure seal. The Compression Hardware Column Components include tubes, frits and compression style end fittings for optimal performance in LC applications. Our LC Column tubes are made from stainless steel and offer excellent chemical resistance. Our frits are designed to match the inner diameter of the tube and are available in standard stainless steel with some titanium and PEEK options as well. End Fittings are available in multiple port geometries and is manufactured from stainless steel to match the tube and acts to secure the frit and connect to the tubing.
