3.1.2 Spring Rings Consult your Isco Mounting Rings instruction manual for
detailed hardware information.
Stainless steel spring rings simplify probe installation in 6 to 15
inch round pipes. Teledyne Isco offers five diameter sizes: 6, 8,
10, 12, and 15 inches (15.2, 20.3, 25.4, 30.5, and 38 cm). A typical
spring ring is shown in Figure 3-1.
This self-expanding device compresses to slide into a pipe. When
released, the ring secures itself against the wall with an inherent
outward force.

Preparing the Spring Ring:
First attach the bubble line to the bubbler carrier assembly
(contact your Teledyne Isco representative to purchase the
bubbler carrier). Then fit the carrier onto the mounting tabs of
the ring, making sure the tabs completely engage the slots in the
carrier. This method of attaching the bubble line to the ring
allows for easy removal in case service is needed later.
