How to choose the Union?

We are selling two kinds of union now, one is flat seal with gasket, and the other is cone seal.

Please see the picture below.The flat seal is to place O-ring seals, usually made of PTFE, on two contacting planes, and there will be no leakage between the planes.

Cone seal is two surfaces with different slopes extruding each other to form a seal.Please see the picture below.

So what are the advantages and disadvantages of these two kinds of union?and how do we choose?

For the flat seal union,the advantage is that the sealing is very good. However, the disadvantage is the gasket is easy to corrode, short service life, greatly affected by the environment.

For the cone seal union ,the advantage is that the sealing is aslo good.And the material is stainless steel, so corrosion-resistant, long service life, suitable for a wide range of environments.

The two products both have a very good market. So you can choose the one that suits your market.Please you can find our products in https://jinsonfittings.com/product/union-f-f/.
