HySecurity MX3627, Gasket, Shaft Seal
The HySecurity MX3627 shaft seal gasket is a WedgeSmart DC service part used around the arm output shaft. This area is exposed to motion, vibration, weather, and debris, so a proper gasket helps keep the shaft opening protected. A worn or damaged gasket may allow dirt or moisture into a critical moving area, which can lead to corrosion, premature wear, or unreliable wedge movement. This part is not a general-purpose O-ring or generic seal; it is an OEM gasket sized and shaped for the WedgeSmart DC shaft seal location. During replacement, the surrounding shaft surface and hardware should be inspected so a new gasket is not installed over a damaged or dirty sealing surface.

- Service involving shaft seal, wedge pivot, arm output shaft, and related protective components

Technician Note
This is an OEM HySecurity service part. Match the part number, operator model, original assembly, and current parts diagram before ordering. Similar HySecurity parts can look close but may use different dimensions, wiring, connectors, handing, or operating functions.
Before Ordering Checklist
- Confirm the HySecurity operator model and product family.
- Compare the original part number or parts diagram to MX3627.
- Check related components for wear, damage, corrosion, fluid leaks, heat damage, or misalignment.
- Verify voltage, wiring, connector style, mechanical size, handing, and hardware where applicable.
- Do not bypass safety devices, circuit protection, or required entrapment protection while diagnosing the operator.
Professional Advisory
Gate and barrier operators can move heavy equipment and may include stored energy, hydraulic pressure, battery power, and high-voltage circuits. If the system is damaged, leaking, repeatedly tripping a breaker, moving unpredictably, or missing required safety devices, have it inspected by a qualified gate technician before returning it to service.
Product Questions and Answers
What is MX3627 used for?
MX3627 is used to seal the arm output shaft area on supported HySecurity WedgeSmart DC operators.
Is MX3627 the same as MX3594?
No. MX3627 is a shaft seal gasket, while MX3594 is the spring tube top gasket.
When should I replace this gasket?
Replace it when it is torn, flattened, missing, contaminated, or removed during shaft or pivot service.
Can this gasket fix mechanical binding by itself?
Not usually. Binding may involve shaft wear, pivot damage, debris, corrosion, or alignment problems that should be inspected separately.
Does it fit other HySecurity operator families?
Do not assume so. Use MX3627 only where the official parts diagram or original part number confirms compatibility.
