Question by: Harvey H on Feb 4, 2026, 1:46 PM
i’m trying to plumb a tight corner, is this fitting a 90 elbow with a swivel female on one end and a male pipe thread on the other?
Answer by: Customer Support on Feb 6, 2026, 7:23 AM
Function-wise, it’s a 90 degree elbow adapter in the Eaton Aeroquip 2047 series with a 1-11-1/2 female NPSM internal pipe swivel on one side and a 1-11-1/2 male NPTF external pipe thread on the other.
Question by: Larry T on Jul 9, 2025, 8:37 PM
Got a 1-inch NPT line running to a pump on a paper mill skid and need a 90-degree turn with a swivel on the female end. This the right part for that setup?
Answer by: Customer Support on Jul 11, 2025, 6:04 AM
For a 1-inch NPT configuration with a 90-degree elbow and a female swivel on one end, yes, this fits exactly what you're describing. The female side uses an NPSM internal pipe swivel connection and the male end is NPTF external pipe thread, both at 1-11/2 NPT sizing. Pulp and paper is actually one of the listed application environments for this adapter, so it holds up in that kind of service. The swivel feature on the female port lets you position your line without putting rotational stress on the fitting during installation, which is handy when you're working in tight quarters on skid-mounted equipment.
