S-90097A115 0.088" ID x 0.175" OD Insulating Washers

Key Features & Benefits at a Glance

• Excellent Electrical Insulation & Corrosion Resistance – Nylon construction prevents galvanic corrosion and provides reliable electrical isolation in sensitive assemblies.
• Consistent Performance Across Wide Temperature Range – Maintains structural integrity and function from -40°F to 180°F, suitable for diverse operating environments.
• Enhanced Vibration Resistance & Component Protection – The sleeve design and Rockwell R118 hardness absorb shocks and prevent loosening under dynamic loads.
• Precision Fit for No. 2 Screws – 0.088" ID ensures secure seating and uniform load distribution, reducing the risk of fastener failure.
• Lightweight & Chemically Resistant – Nylon material offers low weight and resistance to many oils, solvents, and chemicals, ideal for industrial machinery.
• Full Regulatory Compliance for Global Supply Chains – Meets RoHS 3 and REACH standards, ensuring safe use in regulated markets and electronics.
• Durable, Non-Marring Surface – Off-white nylon is hard enough to resist deformation yet soft enough to protect finished surfaces from scratches.

Professional Applications & Engineering Value

This nylon sleeve washer is engineered to solve critical challenges in electrical enclosures, automotive assemblies, and precision instrumentation. Its sleeve-type design provides superior insulation and spacing control, preventing short circuits and misalignment in No. 2 screw fastening systems. The nylon plastic material ensures consistent performance without swelling or brittleness across a -40°F to 180°F temperature range, making it ideal for applications exposed to thermal cycling. By combining Rockwell R118 hardness with chemical resistance, it extends service life in harsh industrial environments, reducing maintenance needs and improving assembly reliability.

Specification Summary & Compliance

This washer features an ID of 0.088", OD of 0.175", and overall height of 1.05", with sleeve dimensions of 0.112" OD and 1" height. It is designed for No. 2 screw size in the inch measurement system. The product is manufactured to industry standards for dimensional consistency and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety requirements.
