Description
Overview:
The O'Rings 4 Inch for Lever Lock Connections are circular sealing rings designed to restore and maintain a tight seal in standard lever lock hose and pipe couplings. Made from durable elastomer rubber in a round cross‐section, they compress evenly to prevent leaks under vibration and typical operating pressures. Sized for 4 inch (101.6 mm) lever lock systems, they are commonly used on pumps, layflat hose lines, and site water transfer equipment in construction, agriculture, and grounds maintenance. These replacement rings help ensure reliable, leak‐resistant joints between coupling halves, reducing downtime and fluid loss. Identified by Manufacturer Part Number (MPN) 777 400, they are a straightforward maintenance item for keeping hose assemblies and plant equipment connections secure and efficient.
Key Features:
- 4 inch (101.6 mm) size for standard lever lock couplings on hoses and pipework
- Resilient elastomer rubber for dependable sealing and long service life
- Uniform compression for a consistent, leak‐resistant seal across the joint
- Helps maintain performance under vibration and repeated coupling/uncoupling
- Simple to fit: sits in the coupling groove with no special tools required
- Suitable for water and general fluid transfer tasks common on site and farm use
- Black finish, round profile to match typical lever lock groove geometry
- Cost‐effective preventive maintenance to reduce fluid loss and clean‐up
- Compatible with typical 4 inch (101.6 mm) lever lock hose and pipe connectors
- Reusable if undamaged; easy to inspect and replace during routine servicing
Typical Applications:
Used to seal 4 inch (101.6 mm) lever lock hose couplings on site pumps, dewatering lines, irrigation and slurry transfer, tanker fill/empty points, and general water handling on construction, landscaping, and agricultural equipment. Ideal for maintaining leak control on temporary pipework, layflat hose assemblies, and plant connections exposed to movement and vibration.
