Does the Quick coupling socket with hose end and valve, NITTO KOHKI HI CUPLA, brass require the medium to flow from the socket to the plug?

Yes. The Quick coupling socket with hose end and valve, NITTO KOHKI HI CUPLA, brass requires the medium to flow from the socket to the plug. The product note explicitly states the medium must flow in that direction. Operating parameters (working pressure, temperature range, flow rates) are specified for that correct flow orientation.

Can Quick coupling socket with hose end and valve, NITTO KOHKI HI CUPLA, brass be used with fluids other than water?

Quick coupling socket with hose end and valve, NITTO KOHKI HI CUPLA, brass is designed for water installations; brass body, NBR seal, working pressure 10 bar and temperature range â20Â°C to +80Â°C. Use with other fluids is not recommended without verification: compatibility depends on fluid chemistry, temperature and seal material. NBR is generally compatible with water, oils (mineral), air, and some glycol solutions but is attacked by ketones, strong acids/alkalis, aromatic hydrocarbons and some solvents. For aggressive chemicals, fuels, high-temperature fluids or food/pharmaceutical use, consult Nitto Kohki or supplier and choose appropriate seal material and certification. Also respect flow direction (socketâplug) and stated pressure/temperature limits.

Is Quick coupling socket with hose end and valve, NITTO KOHKI HI CUPLA, brass suitable for outdoor water installations?

Yes. Quick coupling socket with hose end and valve, NITTO KOHKI HI CUPLA, brass is suitable for outdoor water installations given the provided specifications: - Designed for water installations. - Material: brass. corrosion-resistant and commonly used outdoors. - Working pressure: 10 bar (operational up to this limit). - Operating temperature range: -20Â°C to +80Â°C (with NBR seal). suitable for most outdoor climates, though extreme cold below -20Â°C or high temperatures above +80Â°C may affect seals. - Good durability and vibration resistance. beneficial for outdoor use. - Flow rates adequate for various hose sizes at 5 bar. - Note: medium must flow from socket to plug. ensure installation follows correct flow direction. Considerations: - If exposed to seawater or highly corrosive environments, additional corrosion protection or alternative materials may be needed. - In locations subject to freezing, drain or protect the coupling to prevent damage to seals. - Verify compatibility of NBR seals with any additives or chemicals in the water.
