Question by: Don O on Aug 14, 2025, 12:49 PM
porting on this is 3/8 NPTF right? trying to figure out if it'll thread straight into my existing manifold without adapters
Answer by: Customer Support on Aug 15, 2025, 2:28 PM
3/8 NPTF is correct. NPTF is a dryseal thread, so it forms a pressure-tight connection on its own without needing sealant tape in most cases, though a lot of folks still use thread sealant for extra insurance at higher pressures. If your manifold is already tapped for 3/8 NPTF, you should be able to thread directly in. If it's tapped for 3/8 NPT, that's also compatible in most installations since the thread dimensions are the same, but NPTF is the tighter-tolerance version of the two.

Is the 185-E1F directional control valve suitable for use with mineral oils?
Answer by: Customer Support on Oct 23, 2025, 11:47 AM
For fluid compatibility, the 185-E1F valve works well with mineral oils that meet ISO 11158 standards. If you're considering other fluids, it's best to check specific compatibility or request further details.
