Thread Standards

• Metric Heavy (S) Male – DIN 2353 / ISO 8434-1 24° cone, heavy series. It seals on the 24° cone and is built for higher pressures than the light series.

How to Choose

• All three ports are the same size and thread, so it does not matter which way the tee goes in.
• Heavy (S) will not seal in a light (L) port even where the thread starts. Check the series on all three mating nuts.
• Look into each mating cone for a captured O-ring. Plain and O-ring cones do not interchange.

Technicians Advice

The cone does the sealing and the nut only supplies the load. With three cones, inspect all three faces on the bench, because a scored cone will not come good under torque however long the bar is.

Where You’ll Find It

• Metric Heavy (S) Male – European machinery on the pressure side, where working pressures exceed the light series rating.

Cross-Reference

• Metric Heavy (S) Male – DIN 2353 / ISO 8434-1 24° cone, heavy (S) series. Parker EO / EO-2.

Parker, Gates, Aeroquip and Ryco all manufacture to these same standards under their own part numbering, so a fitting built to the standard above will mate with theirs.

Cross-references are given at series level as a guide to the standard, not as a part-for-part substitution. Always confirm the thread form, size and seal type against the port before ordering.
