Overview
A metal-seat non-return cartridge for plastic-housing press-in installation where forward-flow resistance and compact geometry matter.
Construction and interfaces
The maker lists a 6.60 mm body diameter and metal-to-metal seat. The individual product photograph is not an elastomeric 'Zero Leak' variant.
Selection
Check bore geometry, housing retention, forward flow and acceptable reverse leakage. The 75-Lohm catalog value applies to the listed series reference, not the assembled loop.
Configuration options
Housing design and exact cracking-pressure option require the chosen order code and test conditions.
Application limits
A metal-to-metal seat should not be described as leak-free without an exact tested configuration; pressure rating also depends on the plastic housing.
