Description
Sampling high-pressure compressed gases requires flawless seals to ensure accurate pressure step-down and volumetric flow. Over time, exposure to high-velocity process gases and cleanroom sterilization chemicals can cause standard elastomer seals to wear or compress. This Set of 2 Replacement O-Rings provides the exact factory-specified fit for the inlet and outlet ports of both the HPD 1 and HPD 2 units, restoring the device to its original leak-proof operational standards.
Key Features & Benefits
-
High-Pressure Resilience: Designed to withstand the intense physical stress of connecting to active facility compressed gas lines (CDA, N2, Argon) without extruding or failing.
-
Exact OEM Fit: Manufactured to the precise tolerances required for Applied Physics and EMTEK High Pressure Diffusers.
-
Chemical Compatibility: Highly resistant to degradation from standard cleanroom wipe-downs, sanitizers, and sporicides.
Applications
-
Routine preventative maintenance for High Pressure Diffuser assemblies
-
Replacing worn or lost seals to maintain ISO 8573 compliance testing accuracy
