Valco joints
Split pressure joint —— when the nut is tightened, the pressure ring is pressed on the pipe, which provides a reliable guarantee for the connection of metal pipe under high pressure. Due to the rotation of the sealing surface when tightening hard, the integrated press joint (nut and ring) is generally not used (one body).
Valco technology has been leading in the design and manufacture of joints. If the analytical system needs to achieve and maintain the best performance level, the quality considerations should not be ignored, including:
● line does not deform ——Valco the metal ring is inserted into a ring near the end of the pipe, which can prevent the pipe from falling off under high pressure, and the metal ring will not deform the inner part of the pipe. They hardly deform the pipe so that it can usually be used to fix the glass liner. Valco polymer joints can be fixed by friction alone.
● alternative ——Valco joint components are designed with a common guiding depth, allowing replacement when changing connections or replacing joints. The production line of Valco and Cheminert( chemically inert) joints and valves throughout this alternative feature. For the first time, the Valco ring is used to connect the joints of other manufacturers, and its performance is often improved.
● clean and reliable —— our computer CNC machine tool uses water quality lubricant. After each part is finished, the parts are cleaned with a water-soluble cleaning agent and then with hot deionized water. Finally, each metal joint is thoroughly cleaned with 140°C of deionized water vapor. So you don't have to worry about solvent residue.
● precision machining, trimming and tolerances —— some joint manufacturers omit the operation of leveling the bottom of the part at the end of the product's working hours, and do not replace the joint with a typical conical bit, which results in additional dead volume. VICI design and manufacture high precision Valco and Cheminert joint parts by using unique processing technology.

Nuts, screws and nuts |
most Valco joints and valves are provided with corresponding nuts with pressure rings. However, when additional nuts are required, separate orders must be made. Bolt the ports of unused valves, channels, or liquid columns. Close the pipe with a nut with a pressure ring and screw. |

Press ring |
including metal press ring, polymer press ring, integrated fused silica capillary press ring (FS) and detachable fused silica capillary press ring (FSR). |
ZF*/FS* |
Two-way and Multi-way |
Mainly include internal thread / external thread two, variable diameter two, three-way, four-way and multi-way. |

Filter |
Valco unique, patented product filter design has minimal intrinsic volume and simplifies the replacement of filter elements. The filter is made entirely of metal, so it can be used at any temperature used by the instrument. Although the standard metal is 316 series stainless steel, the filter can also be made of various alloys for various practical situations. |

Other types of joints |
Mainly includes internal thread variable diameter joint, syringe joint, HPLC column joint, post-column reaction T joint. |
