Is the JETON Coolant Reducer 1/2" to 1/4" for 1/2" System rated for continuous use at 2 bar and +65°C?

Yes. The JETON Coolant Reducer 1/2" to 1/4" for 1/2" System is rated to operate under working pressures up to 2 bar and temperatures up to +65°C, so it is suitable for continuous use at 2 bar and +65°C as specified.

Can the JETON Coolant Reducer 1/2" to 1/4" for 1/2" System be used with fluids other than coolant (e.g., oils or solvents)?

JETON Coolant Reducer 1/2" to 1/4" for 1/2" System is specified and optimized for coolant use and is made from acetal, which offers good mechanical strength, wear resistance and moisture resistance. Acetal is chemically compatible with many neutral water-based fluids and some light oils, but its resistance to aggressive solvents, strong acids, ketones, chlorinated hydrocarbons or aromatics can be limited. Given the stated working limits (≤2 bar, up to +65°C) and material, you can use this reducer with: - Coolants and water-based cutting fluids (recommended). - Some light mineral oils and non-aggressive lubricants (likely acceptable, but verify fluid formulation). Avoid using it with: - Aggressive solvents, strong acids/alkalis, ketones (e.g., acetone), aromatics or chlorinated solvents — these can swell, crack or degrade acetal and compromise seals. - Fluids at higher pressures or temperatures than rated. If you plan to use oils or solvents, confirm chemical compatibility of the specific fluid with acetal (or consult the fluid manufacturer) and ensure operating pressure/temperature stay within the reducer’s ratings. For aggressive chemicals or harsher conditions, choose a fitting made from a chemically resistant material (e.g., PTFE, stainless steel).
