Question by: Pete E on Sep 9, 2025, 7:38 PM
adapter's 1.75 inches long -- is that gonna be enough clearance for a tight install spot, or do folks usually need a longer version for most setups?
Answer by: Customer Support on Sep 11, 2025, 1:44 PM
At 1.75 inches overall length, it fits pretty well in most standard hydraulic connections configurations where space is at a premium. That said, tight quarters with stacked fittings or close bracket mounts can sometimes make even a short adapter awkward to thread in. If you know the exact clearance you're working with, compare it against that 1.75 inch figure before committing. For most bench or inline applications it clears without issue.
