Question by: Sherry G on Oct 10, 2025, 11:29 AM

What size bolts does this use? Just wanna make sure I have 'em on hand before I start.

Answer by: Customer Support on Oct 12, 2025, 6:19 AM

The kit comes with four grade 8 hex bolts, so you shouldn't need to source any separately for installation.

Question by: Ray M on Jul 4, 2025, 4:35 PM

Running a system on petroleum-based hydraulic fluid around 2500 PSI. This a Code 61 flange setup, just want to make sure the o-ring that comes with it ain't gonna give me trouble down the road.

Answer by: Customer Support on Jul 6, 2025, 12:45 PM

Buna-N handles petroleum and water-based hydraulic fluids without issue, and 2500 PSI sits well within the 3000 PSI rated capacity of this kit. The included 90 durometer o-ring gives you a firm, reliable seal under those conditions. Only time you'd need to look at a different o-ring material is if your fluid type or operating temperature pushes outside what Buna-N can handle, which for standard petroleum fluid at normal system temps, you're not going to hit that wall.
