Copper Washers NEO tools 150 pcs — model 11-979

Pack of 150 copper washers from NEO tools, model 11-979. These flat copper pads serve as sealing and electrically conductive washers for plumbing fittings, hydraulic connections and electrical grounding. Supplied as a bulk set, the washers are made of malleable copper that conforms to mating surfaces to form a tight seal and maintain conductivity where required. The set is intended for repair, maintenance and assembly tasks that require corrosion-resistant soft-metal seals.

Advantages

Copper washers provide reliable sealing performance due to copper's softness and ability to deform to fill surface irregularities. The metal's natural conductivity makes these washers suitable for grounding and electrical connections while also resisting corrosion in many common environments. Supplied in a large quantity, the bulk pack reduces the need for frequent reordering and is convenient for workshops, service vehicles and maintenance crews.

Suitable for

• Sealing threads and fittings in plumbing and hydraulic systems
• Electrical grounding contacts and conductive joints
• Automotive repairs where soft metal crush washers are required
• General maintenance, assembly and HVAC tasks requiring corrosion-resistant seals

Key specifications

• Material: copper (soft, malleable)
• Form: flat washer / crush washer style
• Quantity: 150 pieces per pack
• Typical applications: sealing, electrical conductivity, grounding
• Corrosion behaviour: resistant in common environments; suitable for contact with water and fuel lines when copper is appropriate

How to use

Select the copper washer that matches the bolt, stud or fitting diameter and place it between mating surfaces before tightening. For sealing applications, tighten to the specified torque so the washer deforms slightly to create a metal-to-metal seal; avoid over-torquing which can lead to excessive deformation or damage. For electrical grounding use, ensure clean contact surfaces free of paint, oxide or debris to maintain conductivity. Replace washers after disassembly if they appear flattened, cracked or otherwise compromised.

Usage recommendations

Store in a dry environment to limit surface oxidation and keep washers sorted by size for quick selection. Use appropriate personal protective equipment when working with fittings and hydraulic lines. For applications requiring non-reactive or lead-free alloys, verify material compatibility before installation.
