Swagelok's VCR® Metal Gasket Face Seal Fitting is the preferred fitting in the semiconductor industry for high-purity gas delivery systems. It offers the high purity of a metal-to-metal seal, providing leak-tight service from vacuum to positive pressure. The seal on a VCR assembly is made when the gasket is compressed by two beads during the engagement of a male nut or body hex and a female nut. This makes it a terrific make or break point due to its near zero clearance requirements and high vacuum capabilities. The VCR fitting design has been helium leak tested to a maximum leak rate of 4x10–9 std cm3/s with silver-plated and copper gaskets and to a maximum leak rate of 4x10–11 std cm3/s with unplated gaskets.
The VCR fitting is designed for some of the most demanding applications in the industry. It must maintain a leak-tight seal on the most highly toxic, corrosive and flammable fluids ever developed.
It's crucial, then, to understand the sealing principles behind the VCR fitting install it properly. We have seen skilled contractors assemble systems that pass initial leak tests with flying colors, then develop leakage months after the installation. Small leaks in a gas system may go undetected for years. Undetected fugitive emissions from fitting connections waste money and have the potential to hurt people and the environment.
On Aug. 12 we'll present a two-hour training session in our Fremont facility that will cover all the critical elements of installing VCR fittings. We cover 6 main topics including key design elements of face seal fittings, proper installation techniques, proper welding procedures and precautions, and troubleshooting exercises.
This is a hands-on training session so you will practice correctly assembling VCR Metal Gasket Face Seal fittings. The session is designed for fabricators, contractors, technicians, engineers, procurement personnel, anyone who is involved in the design, installation and use of a VCR fitting.
We will also be offering our tube fittings safety and tube bending seminars that week as well. Quantity discounts available for attendance to multiple training seminars or for three or more people from the same company that attend the same training seminar.
This video gives you a taste of what we'll cover, though it's no substitute for hands-on instruction.
