Made of quality elastomer, the face seal is typically used at the joint between two steel pipes in hydrostatic testing to offer leak-proof retention of hydraulic oil in the radial direction with respect to the axis of the seal. Because the face seal is most commonly employed in static applications, it is often thought of as a static seal.

This series of industrial seal is constructed in accord with API 5CT/ISO11960:2011 standards. Note that during the hydraulic testing it is important to maintain balance between oil and water pressure. When pressurizing or discharging the pipe, do it progressively and gently. This is to protect the face seal from potential risks of damage due to abrupt pressure change.
