Our Retainerless Design
The retainerless design provides higher integrity on high pressure, ensuring no concerns about leakage. The new design, without pipe plugs or holes through the body, completely eliminates leakage to the atmosphere. It is with the following advantages:
- No screwed body plugs
- No leak path to atmosphere
- Emissions free design
- No Fugitive Emissions
