Product Questions & Answers

what's the fluid temperature range on this inlet cover? running standard buna-n seals and want to make sure we're good before we swap it in

Question by: Tammy M on Jan 17, 2026, 10:31 AM

With the standard Buna-N seals, fluid temperature needs to stay between -4°F and 176°F. As long as your system runs inside that window, you're good to go. If you're seeing temps outside that range on a regular basis, you'd want to look at a different seal option, but for most mineral oil setups running at normal operating temps, these seals hold up fine.

what's the max pressure this thing'll handle running a parallel circuit setup?

Question by: Darryl W on May 11, 2025, 4:36 PM

For parallel or tandem circuit configurations, the SD16 handles up to 4600 PSI. If you're running a series circuit instead, that ceiling drops to 3050 PSI. Worth knowing before you spec it in, since the difference is significant depending on how your system is laid out.
