Service Recommendations For Metric 24° O-Ring Seal DIN 20078

NOTE: These fittings are also referred to as EO and EO-2 Bite Type or Ermeto style fittings.

IMPORTANT: In this style of fittings, there are "heavy" and "light" designs. Usually "heavy" is used for pressure lines and "light" is used for return lines.

Some "heavy" and "light" sizes can be threaded together but do not seal properly. Be sure not to mix "heavy" and "light" designed fittings.

1. Inspect the fitting sealing surfaces. They must be free of dirt or defects.

2. Inspect the O-ring. It must be free of damage or defects.

3. Index angle fittings and tighten by hand pressing joint together to insure proper seal.

4. Tighten nut (A) hand tight and then approximately an additional 1/4-1/3 turn using a wrench.
