This EX-CAP is only 1” taller than your average locking well plug.
This line drawing illustrates the EX-CAP and its counterpart the Quick Connect. Together, they open the self-sealing spring-loaded valve in the EX-CAP for gas or liquid to be removed, sampled, or pressure checked, all without the removal of the Cap. The EX-CAP is made entirely of reinforced chemical resistant nylon and has a stainless steel, easy to use, flip-down locking hasp which allows you to secure the cap with any #1 padlock. The EX-CAP is currently sold in three sizes, 1”, 2” & 4”. The EX-CAP is a permanent remediation tool for the sampling or testing of air & water. The EX-CAP works with almost any situation involving negative or natural pressure such as vapor extraction systems, monitoring wells, methane gas, and radon detection. The snap-on feature of the EX-CAP is a brass self-sealing, quick disconnect couple with .28 vacuum (in./Hg) virtual resistance. It adapts quickly to most any vapor analyzer, vacuum gauge, or peristaltic pump. The EX-CAP has a pull-away chemical resistant dust cover to protect the coupling’s outer face when not connected.
The EX-CAP for “Water” has the ability to provide up to one GPM of fluid or a deep gas sample through its nylon compression fitting port on the bottom side, where an umbilical tube would be attached and set into the well at the desired depth.
