Question by: Glen S on Oct 4, 2025, 6:46 AM
got a port that’s JIS, will this plug actually match that G 1/8 - 28 thread?
Answer by: Customer Support on Oct 5, 2025, 9:05 PM
The key detail is the male Side 1 thread callout, which is G 1/8 - 28 and marked as JIS type. It is meant to seal hydraulic ports that conform to Japanese Industrial Standard thread specs in that size.
