HySecurity MX4807, KIT, GASKET/SEAL, 816
The HySecurity MX4807 gasket/seal kit is used to restore the weather barrier on select HySecurity Model 816 operator enclosures. On outdoor gate operators, the gasket is more than a cosmetic part. It helps keep moisture, wind-blown dust, insects, and debris away from control electronics and internal components. When the gasket becomes brittle, flattened, torn, or loose, water can track into the cabinet and cause corrosion, nuisance faults, connector problems, or premature component failure. MX4807 should be selected when the installed parts diagram identifies the Model 816 gasket/seal kit. Before replacing the seal, the technician should also check the enclosure lip, hinge, latch, and cover alignment so the new gasket compresses evenly.

Technician Note
If the old gasket failed because the cover is twisted or the latch is loose, replacing the seal alone may not stop water intrusion. Clean the mating surfaces and check compression after installation.
Before Ordering Checklist
- Match the installed part number to MX4807 or a confirmed HySecurity parts diagram reference.
- Verify the operator model, generation, voltage, and controller family before ordering.
- Inspect related hardware, connectors, covers, seals, and mounting points for damage before reusing them.
- Do not substitute a similar-looking HySecurity part unless the parts diagram confirms the same application.
- Confirm the product is for Model 816 and not another HySecurity enclosure series.
Professional Advisory
Do not ignore water intrusion inside a gate operator. Moisture around controls or wiring should be corrected by a qualified gate technician before the operator is returned to service.
Product Questions & Answers
What does the MX4807 kit replace?
It replaces the gasket or seal material used on select HySecurity Model 816 operator enclosures.
Is this a universal HySecurity weather seal?
No. MX4807 should be used only where the Model 816 parts diagram or service documentation calls for this gasket/seal kit.
What symptoms point to a failed gasket?
Water marks, dust buildup inside the cabinet, loose or torn gasket material, corrosion, or nuisance electrical faults after rain can point to a sealing problem.
Should the cabinet be inspected before installing the new seal?
Yes. Check the cover, hinge, latch, screw holes, and gasket channel so the replacement seal compresses properly.
Can a gasket kit fix a bent cover?
No. A bent or warped cover may still leak even with a new gasket. Damaged cover hardware should be repaired or replaced as needed.
