NICE / APOLLO A2025, SEAL
The Nice Apollo A2025 is a replacement seal used in the front housing and cover tube area of compatible Apollo 416 and 816 style linear actuators. This seal helps protect the internal screw-drive components from moisture, dirt, insects, and debris. It is commonly replaced when the actuator is opened for service, when the old seal is cracked or missing, or when water intrusion has contributed to premature wear inside the housing. A damaged seal can allow contamination around the extension tube, main screw, gear nut, and front housing parts, which may lead to noisy operation, binding, corrosion, or accelerated wear. A2025 should be matched to the exact actuator housing diagram and should not be confused with the rear limit cap and seal kit.

Technician Note
When a seal fails, look for the reason. Bent tubing, worn bushings, old grease, corrosion, or poor actuator alignment can damage the replacement seal if the underlying issue is not corrected.
Before Ordering
- Confirm the installed front housing diagram lists A2025.
- Decide whether the repair needs the seal only or the larger A2024K cover tube and seal housing kit.
- Inspect the extension tube, main screw, gear nut, and housing for corrosion or scoring.
- Check actuator alignment and gate movement before reassembly.
- Do not use sealant or field modifications that interfere with actuator travel.
Professional Advisory
Gate operator parts should be installed with power disconnected and the gate secured against movement. Actuator repairs can affect travel limits, force, and safe gate movement. For electrical diagnosis, internal actuator service, or any unsafe gate condition, use a qualified gate technician. Do not bypass photo eyes, safety edges, alarms, or other required safety devices.
Important Ordering Warning
A2025 is a seal only. If the cover tube, seal housing, or extension tube is damaged, additional parts may be required.
Product Questions & Answers
Where is the A2025 seal used?
It is used in the front housing/cover tube area of compatible Apollo 416 and 816 style actuators.
Is A2025 the same as the A2010 kit?
No. A2025 is a front housing seal, while A2010 is a limit cap and seal kit used around the rear/internal limit area.
What happens if the seal is damaged?
A damaged seal can allow moisture and debris into the actuator, causing corrosion, noise, binding, or premature wear.
Should I order A2024K instead?
Order A2024K if the cover tube or seal housing kit is needed. Order A2025 when the parts diagram and repair call for the seal only.
Can I replace the seal without checking other parts?
It is better to inspect the extension tube, main screw, gear nut, bushings, and housing while the actuator is open.
