Description
Overview:
This rubber washer is a flat sealing ring for 2" (50.8 mm) hose couplings used on pumps, suction and delivery hoses, and general fluid transfer equipment in construction, agriculture, landscaping, and facilities maintenance. Made from durable black rubber, it provides a tight, leak-resistant seal between coupling faces to reduce liquid loss and air ingress. Sized precisely at 42 mm inner diameter, 57 mm outer diameter, and 3 mm thickness, it fits the groove of standard 2" hose couplings while maintaining adequate contact area for reliable sealing. It is straightforward to fit and replace during routine maintenance and is suitable for both professional and DIY use where dependable hose connections are required. Manufacturer Part Number: 829 200.
Key Features:
- For 2" (50.8 mm) hose couplings in water and general-purpose fluid transfer
- Precise dimensions: 42 mm I/D, 57 mm O/D, 3 mm thick for a snug, secure fit
- Flat-profile sealing face to help achieve consistent, leak-resistant joints
- Hard-wearing black rubber designed for repeated coupling and uncoupling cycles
- Helps prevent air ingress on suction lines, supporting pump prime retention
- Quick, tool-free installation in most standard coupling housings
- Cost-effective service item ideal for preventative maintenance schedules
- Suitable for use in industrial, agricultural, and domestic settings where 2" hose couplings are used
- MPN: 829 200 for easy identification and reordering
Typical Applications:
Used to seal 2" (50.8 mm) suction and delivery hose couplings on site dewatering pumps, transfer pumps, irrigation setups, washdown systems, and tank-to-hose connections. Common on building sites, farms, landscaping projects, utilities maintenance, and emergency pumping tasks. Ideal as a replacement washer when connections begin to weep, when hoses are reconfigured, or during scheduled servicing to maintain reliable, leak-reduced performance.
