Unlike standard metal washers that can corrode in humid environments or react with certain materials, PVC offers inherent resistance to moisture and chemicals. This makes them particularly suitable for plumbing fixtures, bathroom hardware, and hose connections where longevity and a reliable seal are paramount. The precise M1.7 metric sizing ensures a proper fit, reducing the risk of leaks and component damage. Each pack contains 300 washers, providing ample supply for multiple repairs and projects. **Ideal for Plumbing & Fixture Repairs** — These washers are best suited for light-duty sealing applications in bathrooms, kitchens, and plumbing systems, particularly where metal washers might corrode or cause galvanic reactions. They are excellent for door handles, towel bars, and hose connections. Individuals seeking washers for heavy-duty structural applications or high-pressure industrial machinery should consider metal alternatives. If you require washers for large-diameter bolts or significant load-bearing surfaces, these smaller PVC washers may not be sufficient. For general-purpose metal fastening, standard steel or stainless steel washers are typically recommended. ## How to use 1. Confirm that the screw or bolt requiring a washer is an M1.7 metric size. Ensure the HARFINGTON washer's inner diameter (1.7mm) matches the fastener diameter. — Identify the Correct Fastener 2. Ensure the surfaces where the washer will be placed are clean, dry, and free from debris. This is crucial for achieving an effective seal and preventing leaks. — Prepare the Surfaces 3. Slide the HARFINGTON M1.7 PVC washer onto the fastener. Position it between the fastener head and the material, or between two surfaces, to distribute pressure and create a seal. — Install the Washer 4. Tighten the fastener securely. Test the repaired component (e.g., faucet, door handle) to ensure it is stable, leak-free, and functions correctly. — Tighten and Test ## Product details | Field | Value | |---|---| | Primary Material | Polyvinyl Chloride (PVC) | | Key Properties | Wear-resistant, Rust-resistant, Corrosion-resistant, Moisture-resistant, Good sealing, Pressure resistance | | Allergens | Contains lead and lead compounds (California Prop 65 warning) | | Application | Repairing junctions on door handles, towel bars, hoses, valves, and plumbing. | | Installation | Easy to install, designed to reduce friction, prevent leakage, loosening, or pressure scattering. | | Usage Frequency | As needed for repairs and maintenance. | | Cost per use | 300 washers at ₹1,128 — ₹3.76 per washer | | Shelf life after opening | Indefinite (non-perishable material) | | Contraindications | Not suitable for heavy-duty structural applications, high-pressure industrial machinery, or as a replacement for metal washers in high-load scenarios. | | Allergens / common irritants | Contains lead and lead compounds (California Prop 65 warning) | | Brand | HARFINGTON | | Color | Clear | | Material | Polyvinyl Chloride (PVC) | | Washer Type | PVC Flat Washer | | Inner Diameter | 1.7mm (0.07 inches) | | Outer Diameter | 5mm (0.2 inches) | | Thickness | 0.3mm (0.01 inches) | | Pack Quantity | 300 pieces | | Country of Origin | Not stated by manufacturer — US retail version, sourced from authorized US retailers | ## Frequently asked questions ### Are these HARFINGTON PVC washers safe for use in India? Yes, HARFINGTON M1.7 PVC washers are safe for use in India for their intended applications. They are made from durable PVC material, offering corrosion and moisture resistance suitable for plumbing and fixture repairs. While they contain lead and lead compounds as per California Prop 65, this is a warning for potential exposure during manufacturing and handling, not a contraindication for their use as intended in repairs. Ensure proper installation for optimal performance. ### How do I choose the right size HARFINGTON washer for my application? To choose the right size, confirm your fastener's metric size. These HARFINGTON washers are M1.7, meaning they fit screws or bolts with a 1.7mm diameter. The inner diameter is 1.7mm, outer diameter is 5mm, and thickness is 0.3mm. Always check the dimensions against your specific needs to ensure a proper fit and effective sealing. ### What are the benefits of using PVC flat washers over metal ones? PVC flat washers offer excellent corrosion and moisture resistance, making them ideal for plumbing and bathroom applications where metal washers might rust or degrade. They also provide a non-metallic seal, reducing friction and preventing potential galvanic reactions. These HARFINGTON washers are designed to prevent leaks and loosening, offering a durable solution for specific repair needs. ### Can these washers be used for heavy-duty applications? No, these HARFINGTON M1.7 PVC flat washers are intended for light-duty sealing and repair applications such as door handles, hoses, and valves. They are not suitable for heavy-duty structural applications, high-pressure industrial machinery, or as replacements for metal washers in high-load scenarios. For such uses, metal washers are recommended. ### What is the shelf life of HARFINGTON PVC washers? HARFINGTON PVC washers are made from a non-perishable material and have an indefinite shelf life when stored properly. They do not degrade over time due to environmental factors like moisture or rust, ensuring they remain effective for future repairs. ### How do I ensure proper installation for sealing performance? To ensure optimal sealing performance, confirm the PVC sealing gasket is properly installed in the desired position. The washer should fit snugly around the fastener and between the surfaces being joined. Ensure the surfaces are clean and dry before installation. Proper placement is key to preventing leaks and maintaining stability. ### Are there any side effects of using these washers? The primary concern noted is the presence of lead and lead compounds, as indicated by the California Prop 65 warning. While this is a manufacturing and handling warning, it's advisable to wash hands after handling. For their intended use in sealing applications, there are no direct 'side effects' on the components they are used with, provided they are the correct size and properly installed. ## Compliance No product-specific compliance warnings identified.
