versions. Our new Finned Top version has been upgraded to include cooling fins on the body of the seal to improve its cooling features and an optional flushing port.
The first generation is still available for customers preferring that design, or applications requiring exotic metals,
such as MONEL 400, HASTELLOY, or Tantalum.

HASTELLOY C bodies; 316L stainless steel, MONEL,

t The XR-Series offers customers a leak-proof, tamperproof, lower cost alternative to an individual gauge and
diaphragm seal. The XR-Series increases worker safety
by reducing potential leaks in your process by welding the gauge to the seal and including our Model 1981
process gauge with a seamless bourdon tube. Many
companies specify seamless tubing throughout their
plants for their process lines, yet they use gauges that
have welded tubing. The Model 1981 gauges starts with
seamless tubing for our bourdon tubes, which provide a
seamless solution throughout your process.

SEAL FILL FLUID: DC 200 silicone standard; other fills available
upon request
OPTIONS: Orifice restrictors on gauge; flush port on seal, StaKool™ cooling element, shatter-resistant window on gauge,
and capillaries
