Question by: Howard K on Mar 17, 2026, 4:13 PM
got a 3/8-18 male NPT port, will this countersunk hex plug screw right in?
Answer by: Customer Support on Mar 19, 2026, 6:20 AM
The key detail is the thread. This part has a 3/8-18 male NPT thread, so it matches ports and fittings that are also 3/8-18 NPT female.
