Stainless Steel Vapor Pin® Sampling Device

The Stainless Steel Vapor Pin® Sampling Device connects to ¼-inch sample tubing (typically Nylon or Teflon®) with softer tubing, preferably Tygon®. Because stainless steel is more durable than brass and more corrosion resistant, we recommend stainless steel for long-term installations and in corrosive environments. Brass Vapor Pin® devices are less durable than stainless steel, but they can be reused repeatedly with proper care. We recommend brass Vapor Pin® devices for short-term installations, especially those installed in the stick-up configuration.
