Description
Overview:
The Bonded Seals M20 for Hydraulic Systems - 50 Pack are metric sealing washers used to create a tight, reliable seal under bolt heads and adaptor faces in hydraulic and plumbing circuits. Each seal combines a metal washer with a bonded rubber sealing ring that compresses to prevent fluid bypass. Sized for M20 threads (20 mm nominal diameter), they suit ports, banjo fittings, and hose adaptors on plant, agricultural, and garden machinery such as excavators, tractors, log splitters, and pressure washers. These are often chosen where a compact, face-seal solution is preferred over thread sealants. Durable construction supports long service in demanding environments with vibration and temperature change. Supplied in a workshop-friendly pack of 50. Manufacturer Part Number (MPN): 915 615.
Key Features:
- Metric M20 size for 20 mm ports, adaptors, and banjo bolts
- Metal washer with bonded rubber insert for a positive face seal under compression
- Helps prevent leakage in high-pressure hydraulic and plumbing connections
- Stable sealing performance under vibration and thermal cycling
- Simple to fit: place between mating faces; no special tools required
- Consistent dimensions for predictable tightening and alignment
- Compact sealing solution where thread sealants or O-rings are unsuitable
- Pack of 50 for servicing multiple fittings and keeping spares on hand
- Suitable for construction, agricultural, automotive, and garden machinery systems
- Reference for identification: MPN 915 615
Typical Applications:
Sealing around screw plugs, hose tails, adaptors, and banjo bolts on pumps, cylinders, valve blocks, and power packs. Common on excavators, loaders, dumpers, tractors, mowers, pressure washers, compactors, and log splitters. Used on return and pressure lines, test points, and manifold faces where a flat, robust seal is required without excessive torque.
