Camlock Gasket Rubber Buna 50mm

The 50mm (2") Buna-N (Nitrile) Camlock Gasket is a heavy-duty replacement seal designed for quick-connect hose fittings used in water, oil, and fuel transfer. This gasket sits inside the female coupler, providing the critical leak-proof compression seal when the cam arms are locked down, making it an essential spare for Pascali Pump suction lines and agricultural sprayers in the Heidelberg - GP region.

Technical Specifications

• Size: 50mm / 2" (Standard for medium-volume transfer hoses).
• Material: Buna-N (Nitrile Rubber) – High-grade NBR compound.
• Profile: Flat washer with precision-cut edges for a flush fit.
• Temperature Range: 30C to 100C.
• Compatibility: Fits all standard Type B, C, D, and DC 50mm female camlock couplers (Aluminum, Polypropylene, or Stainless Steel).

Key Performance Features

• Oil & Fuel Resistance: Unlike standard EPDM rubber, Buna-N is specifically engineered to handle petroleum-based products, hydraulic oils, and diesel without swelling or degrading.
• Suction Integrity: Provides a high-vacuum seal, which is critical for the suction side of a 1.1kW Pascali Pump. A worn gasket here will cause the pump to draw air and lose its prime.
• Compression Recovery: The rubber maintains its shape and "spring" even after being clamped under high pressure for long periods during the Easter 2026 irrigation cycle.
• Abrasive Resilience: Designed to withstand the grit and sediment found in dam water or borehole lines, ensuring the seal doesn't "pit" or leak.
• UV Resistance: Formulated to resist the intense Gauteng sun, preventing the rubber from becoming "chalky" or cracking during the dry Winter Bulk 2026 months.

Installation & Professional Tips

• Removal: Use a small flat-head Kaufmann screwdriver to gently pry the old, flattened gasket out of the female coupler groove. Be careful not to scratch the metal or plastic seating surface.
• Cleaning: Before inserting the new 50mm Buna Gasket, wipe the internal groove with a Shield Microfibre Cloth to remove any sand, lime-scale, or old oil residue.
• Seating: Press the new gasket firmly into the groove with your thumbs. It should sit flat and "snap" into place. If it is bunched or protruding, the cam arms will be impossible to close.
• Lubrication: For the first use, apply a tiny smear of silicone grease or dish soap to the gasket surface. This allows the male adapter to slide in easily and prevents the rubber from "pinching" or tearing when you lock the cam arms.
• Alignment: If the coupler still leaks under pressure, check the male adapter (the "plug") for nicks or dents. Even a brand-new Buna gasket cannot seal against a damaged metal face.

Common Use Cases

• Water Tankers: Sealing the suction and discharge hoses on mobile water carts.
• Agricultural Sprayers: Ensuring leak-proof connections for liquid fertilizers and pesticides.
• Pump Suction Lines: Connecting 50mm Heliflex hose to Pascali or petrol-driven trash pumps.
• Industrial Wash-down: Quick-connect points for high-volume factory cleaning systems.

Pro Tip: If your camlock arms are becoming increasingly difficult to close, do not force them with a hammer. This usually indicates the gasket has swollen due to chemical incompatibility or is improperly seated. Always keep a spare 50mm Buna Gasket in your Kaufmann tool chest, as these are the most common "point of failure" in any high-volume fluid transfer system.
