Spacer ring flange pair that holds a fixed joint length with a machined spacer ring, so wafer valves and meters go in or out without re-piping.QS Flange: Quanzhou Spacer Ring Flange
Orifice weld neck flange pair: two butt-welded hubs clamp an orifice plate, and pressure taps drilled in the flange body feed the flow transmitter.QS Flange: Zhangzhou Orifice Weld Neck Flange
Socket weld flange that takes the pipe end in a recessed socket and seals it with one external fillet weld, for compact small-bore lines.QS Flange: Putian Socket Weld Flange
Forged stainless steel flange per ANSI B16.5, 150LB to 2500LB, 1/2 to 24 inch, slip on, weld neck and blind types for construction, chemical and energy service.QS Flange: Xiamen Stainless Steel Flange
SAE Code 62 Flange

One-Minute Overview
- Code 62 identifies the high-pressure series of the SAE J518 flange family.
- Available with an O-ring side, a flat side, or as a complete set.
- Bolted flange connection used on hydraulic pumps, motors and manifolds.
- The four-bolt pattern gives a compact, serviceable joint for high-pressure lines.
SAE code 62 flanges are the high-pressure series of the SAE J518 four-bolt flange family used throughout hydraulic systems. The code sets the working-pressure family: where code 61 covers the medium-pressure range, code 62 serves high-pressure pump, motor and manifold connections. Flanges are supplied with an O-ring side, a flat side, or as a complete set, depending on the hydraulic system requirements.
The four-bolt joint makes assembly and service easy in tight spaces, and the SAE J518 pattern keeps heads, caps and adapters interchangeable. Select the O-ring configuration for the sealing side of the connection and the flat configuration where a flat-machined port is used.
FAQ
Q1. What does the code 62 designation mean within the SAE J518 family?
Code 62 is the high-pressure series of the SAE J518 four-bolt flange family, where code 61 covers the medium-pressure range. The code tells you which working-pressure family the head, cap or adapter belongs to, so parts from the same code stay interchangeable on pump, motor and manifold connections.
Q2. O-ring side, flat side, or the full set — which one do I need?
It depends on the port you are sealing. Choose the O-ring configuration for the sealing side of the connection, and the flat configuration where the port is flat-machined. If you are building the joint from scratch, the complete set gives you matching halves without hunting for the second piece.
Q3. Why do hydraulic people like the four-bolt pattern so much?
The four-bolt joint makes assembly and service easy in tight spaces — think crowded pump skids and manifolds — and the SAE J518 pattern keeps heads, caps and adapters interchangeable. Fewer odd tools, faster swaps, and one code tells you the pressure family before you even pick up the wrench.
Q4. How long does production take?
Standard sizes are typically ready within 30 days, and in-stock items ship immediately. Larger or custom orders are confirmed date by date, because the schedule depends on quantity, material, the bolt pattern you specify, and how busy production is when you place the order.
