One-Minute Overview

Code 61 flange rated to 3000 PSI for hydraulic systems.
2 inch, carbon steel body with a SAE female NPT threaded connection.
Blank-oiled finish protects the machined surface in storage and transit.
Bolts and O-ring supplied as spare parts for heavy machinery and construction equipment.

This code 61 flange covers the medium-pressure range of the SAE J518 flange family, rated to 3000 PSI for hydraulic systems. It is a 2 inch, carbon steel part with a SAE female NPT threaded connection, finished in blank oil and supplied with bolts and an O-ring as spare parts.

Name: Code 61 Flange
Size: 2 Inch
Pressure: 3000 PSI
Material: Carbon Steel
Type: SAE Female NPT Thread
Finish: Blank Oiled
Spare Parts: Bolts and O-ring

The SAE female NPT thread makes a secure, leak-free connection to the mating hydraulic fitting, and the SAE J518 family pattern keeps heads, caps and adapters interchangeable on pumps, motors and manifolds. The carbon steel body gives the strength heavy-duty cycles demand, while the blank-oiled coating guards the machined surfaces against corrosion and extends service life until the flange is installed. Typical duty includes hydraulic systems in heavy machinery, construction equipment and industrial installations where 3000 PSI lines must stay reliable shift after shift. Confirm the working pressure and the thread size of the mating part before ordering, and keep the O-ring and bolts on hand for the first assembly.

FAQ

Q1. What does the code 61 designation mean in the SAE J518 family?

Code 61 is the medium-pressure series of the SAE J518 flange family, where code 62 covers the high-pressure range. This flange is rated to 3000 PSI, which fits hydraulic circuits working inside that pressure band on pumps, motors and manifolds.

Q2. So what actually shows up with the flange?

A 2 inch carbon steel code 61 flange with a SAE female NPT thread and a blank-oiled finish, plus bolts and an O-ring as spare parts. The hardware rides along so the first assembly does not stall waiting for a trip to the store. Check the mating thread and pressure before ordering.

Q3. Why is it covered in oil — did someone get careless?

Not at all. The blank oil is the finish: a protective coat that keeps the machined surface from corroding in storage and transit. Wipe it off at assembly if your hydraulic fluid is picky, and the flange goes to work with its 3000 PSI rating untouched.

Q4. What payment terms do you accept?

T/T, L/C at sight and other internationally accepted terms. The exact terms are agreed with you before production starts, because the payment schedule has to match the order value, the shipping method and the delivery schedule you need — which is also why we confirm them up front rather than after shipment.
