TEMPERATURE DATA
The Dry Link Adapter/Coupler assembly has an operating temperature
range of: -20 degrees F to +230 degrees F (-29 degrees C to +110 degrees C), using Fluoroelastomer or EPDM seals and +20 degrees F to +230 degrees F (-7 degrees C to +110 degrees C) using PTFE seals. Seals made of Perfluoroelastomer material may be rated to higher temperatures – consult us.
MATERIALS DATA
Wetted Metal Parts:
All 316 stainless steel (standard), Alloy 20/Carpenter 20 cb-3 (Optional)
*Disc is electroless nickel plated (ENP) to minimize wear and galling.
Main Seals: Choice of PTFE (Teflon®), Fluoroelastomer (FKM, Viton®), EPDM, or Perfluoroelastomer (FFKM, Kalrez®, Chemraz®).

Viton
Can be used for many oxidising acids, petroleum oils, halogenated hydrocarbons, lubricants, hydraulic fluids or organic liquids.
EPDM
Can be used for a variety of industrial chemicals such as dilute acids and most ketones and alcohols. EPDM is not recommended for use with petroleum products.
PTFE
Has outstanding resistance to chemical attack by most chemicals and solvents.
