DILO High pressure tube unions

Built to maintain pressure tightness even under extreme conditions

Do you have to handle high pressures, extreme temperatures, aggressive media or hot vapors with high process reliability? DILO’s high pressure tube unions can help! Our high pressure tube unions remain hermetically sealed even under critical operating conditions.

The secret lies in the high-quality metal-to-metal sealing principle developed by DILO. The high-pressure tube unions are sealed without any intermediate seal compound. The seal is obtained by direct contact of the tongue and groove sealing surface.

Our sealing principle allows permanent pressure tightness up to 1,000 bar and withstands temperatures from -270 °C to +650 °C (dependent on the material used). DILO high pressure tube unions are completely maintenance free and can be loosened and re-connected as often as required, an invaluable property when your pipework systems require frequent maintenance. Our high pressure tube unions allow you to save valuable time and reduce your maintenance costs.
