One-Minute Overview

SAE J518 code 61 flange doubling as a blanking and shipping plate.
1-1/2 inch, Q345B steel, AFC-L type code.
Cuts cost and weight across fluid power systems.
Protects ports in transit and during zero-pressure assembly.

This SAE J518 code 61 flange is built as a blanking and shipping plate rather than a running joint. The AFC-L design covers both a blind plate and a shipping plate, so one part can seal a port in transit and blank it during service. Made from Q345B steel at 1-1/2 inch, it trims cost and overall weight while staying inside the SAE J518 standard.

Name: SAE J518 Code 61 Flange
Standard: SAE J518
Size: 1-1/2"
Material: Q345B
Pressure: Code 61
Type: Blanking Plate, Shipping Plate
Type Code: AFC-L

Blanking plates earn their keep in fluid power systems where a port must stay closed until the machine is commissioned. The shipping plate side protects the circuit in transit so the unit arrives clean, while the blind plate side keeps the port sealed during zero-pressure stages of assembly. Because the design deliberately trims both cost and weight, it suits equipment makers fitting many ports per machine. Match the bolt circle to the mating SAE J518 code 61 head, fit the seal specified for the fluid, and torque the bolts evenly.

FAQ

Q1. So what does this AFC-L plate actually do for me?

It covers two jobs in one part: a blind plate that blanks a code 61 port during service, and a shipping plate that protects that port in transit. Dimensions follow SAE J518, so it mates with standard code 61 heads on fluid power systems.

Q2. Does the plate really save weight, or is that brochure talk?

The saving is real: the design deliberately trims cost and overall weight compared with a full flange connection. Q345B steel keeps the plate strong where it counts, so the economy does not come out of its ability to seal a code 61 port.

Q3. When should a blanking plate be used instead of a live connection?

Use it whenever a port must remain closed rather than carry flow: during shipping, in storage, and through zero-pressure stages of assembly. It protects the circuit from dirt and damage and keeps options open until the final connection is installed.

Q4. How long does production take?

Standard sizes are typically ready within 30 days, and in-stock items ship immediately. Larger or custom orders get a confirmed date per order, because the schedule depends on quantity, material, the bolt pattern you specify, and how busy production is at the moment you order.
