High Temperature General Service Die
Formed Pump & Valve Packing Sets.

Features / Benefits:

• Positive sealing with less gland pressure no binding of valve stem.
• Non-abrasive - sleeves last longer.
• Corrosion inhibited - valve stems last longer.
• Chemical compatibility - reduce inventory costs.
• Low friction - no product dilution from cooling liquids.
• Pre-formed rings - reduce maintenance labour costs.
  

Typical Applications: 

• High-speed pumps, and valves handling steam, condensate, and petroleum products.
• Superheated steam and applications where fire safety is critical such as oil refineries and power plants.
