1. Excellent Air Tightness
  • The unique seal structure realizes excellent airtightness.
  • Metal gasket type with small load on pressure resistant parts even when detaching is repeated.
2. Excellent Installation and Operability/Removing
  • No need for an axial space for detaching the device.
  • Construction instructions include rotation control and overtightening prevention mechanism.
  • Compared to coned and threaded joint, construction with low torque can be done.

Creativity of UPG High Pressure Fittings

3. Excellent Scalability
  • Excellent vibration proof is achieved by separating the part to be sealed and the part receiving the external force.
  • Lineup includes two pressure series: 95 MPa and 50 MPa

1 Seal Performance
( 82MPa )
ᐃ 99.9MPA Specification
However, it is affected by the construction performance and sealing in unstable
ᐃ 21.5MPa Specification ⵔ 95MPa Specification Optimum value to maintain pressure ressistance comes from the coefficient of the fitting's inner diameter, diameter of the sealing surface protuberance and the gasket's inner/outer diameter, the sealing portion was devised.
2 Pressure Resistance

3 Construction Performance ×
Tube threading and additional work on the tip is required

Additional processing is not required on the fitting parts

4 Measures to prevent tubing circulation during construction ×
No co-rotation countermeasure

A ball bearing is inserted in the nut, however it is unsuitable for the high load and corrosion resistance required in outdoor use

The nut's bearing is changed to a thrust bearing, which improves the high load and corrosion ressistance
5 Attachment / Detachment Durability ×
Repeated attaching / detaching and the sealing surface deteriorates

When replacing the gasket, the health of the sealing surface in maintained
