got a shop line that runs up around 200 psi sometimes. is this regulator ok on the inlet side?

Answer by: Customer Support on Jun 26, 2025, 6:10 AM

Max inlet pressure for the 42 Series FlexiBlok regulators is 250 psi, so a 200 psi supply is within its stated limit.

running a pretty big pneumatic setup and need something that can actually handle the flow without choking everything down, this regulator got enough capacity for that kind of demand?

Answer by: Customer Support on Sep 1, 2025, 8:36 PM

At 300 SCFM and 1-inch ports, it's built for high-demand industrial systems. The 42 Series sits at the top of the FlexiBlok lineup for flow capacity, and that's a meaningful number for a line regulator in this size class. If your system is pulling serious air volume, this one won't be the bottleneck.

Will this regulator hold up okay outside, or is it meant for indoor use only?

Answer by: Customer Support on Jul 10, 2025, 4:25 PM

This regulator's aluminum body construction provides durability in industrial environments. Keep in mind the group temperature range is 40-120 °F, so it's best to ensure the environment stays within those limits for optimal performance and longevity.
