Product Questions & Answers (3)

Question by: Kurt P on Jun 10, 2025, 7:34 AM
trying to replace an old flange to pipe adapter, is this one the 1-1/2 code 62 4-bolt flange to 1-1/2 female npt straight style?
Answer by: Customer Support on Jun 11, 2025, 9:35 PM
Match-up wise, it’s a straight steel adapter that goes from a 1.50 inch Code 62 four-bolt flange face on the O-ring half to a 1.50 inch female NPT port. The pad size is 1.5 and it’s listed as fitting 1.5 inch pipe size, so it’s the common 1-1/2 to 1-1/2 flange-to-NPT transition.
Question by: Ray B on Dec 15, 2025, 6:31 PM
Does this adapter come with everything needed to bolt it up, or do I have to track down the hardware separate?
Answer by: Customer Support on Dec 17, 2025, 6:20 PM
Everything ships together. The package includes the mounting bolts, lock washers, and a Buna-N O-ring, so you can go straight to installation without making a separate hardware run.
Question by: Kurt M on Dec 17, 2025, 3:48 PM
Will this flange adapter hold up okay in a hydraulic system running around 3000 PSI?
Answer by: Customer Support on Dec 18, 2025, 8:21 PM
This adapter is designed for high-pressure hydraulic systems, providing a secure, leak-resistant connection between a Code 62 four-bolt flange and a female NPT port. The Buna-N O-ring should provide reliable sealing with standard hydraulic fluids at that pressure.
