Product Questions & Answers (2)

Question by: Gene C on Oct 30, 2025, 10:46 AM
What size flange does this o-ring fit?
Answer by: Customer Support on Oct 31, 2025, 2:09 PM
This o-ring is designed for SAE J518 split flange fittings and adapters that are 0.50 inches.
Question by: Dale M on Jun 13, 2025, 8:02 AM
Got a split flange fitting on a 1/2 inch hydraulic line that needs a new o-ring, this the right size for that?
Answer by: Customer Support on Jun 14, 2025, 11:08 AM
For SAE J518 split flange fittings on a half-inch line, this is the correct o-ring. It carries a dash size of -08 and fits with an inside diameter of 0.734 inches and an outside diameter of 1.012 inches, with a width of 0.139 inches. That geometry is spec'd for the SAE J518 half-inch split flange connection, so it should drop right into place on a standard fitting of that size.
