got a tight spot on a hose run, what are the ends on this elbow adapter?

On the connection side, it is a 90 degree adjustable elbow with a SAE 37 degree male on one end and a BSPP male on the other. The end sizes are 0.4375 for the SAE 37 end and 0.25 for the BSPP end.

Will this elbow adapter hold up in a saltwater environment on my boat?

Dura-Kote plating gives this adapter superior corrosion resistance, which is important for marine applications.
Question by: Chad H on Feb 22, 2026, 7:53 AM
This adapter says it works for marine and offshore drilling, does the coating actually hold up when it's exposed to saltwater or chemical runoff on a regular basis?
Answer by: Customer Support on Feb 23, 2026, 9:06 AM
Eaton Aeroquip put Dura-Kote plating on this one specifically because corrosion is a real concern in those environments. Carbon steel on its own wouldn't cut it for saltwater or chemical exposure, but the Dura-Kote finish is what gives it the durability edge in marine and offshore drilling setups. That's not just a marketing claim either, it's the reason this adapter is listed for chemical processing and food and beverage applications too, where surface integrity matters a lot.
