382 PCS SAE FKM Viton O Ring Assortment Kit - High Temp Oil Resistant

In this review the 382 PCS SAE FKM Viton O Ring Assortment Kit is evaluated as a practical parts kit for technicians, home mechanics and hobbyists who need a wide range of fluorocarbon o rings. The bottom line: it is a useful, organized assortment built to aerospace AS568 sizing that offers broad chemical and temperature resistance, making it worth buying for plumbing, engine, hydraulic and aviation maintenance where high temperature resistance and oil compatibility matter.

Key Features

• Aerospace standard sizes: The set follows AS568 sizing and includes 30 inch ID sizes so users can match rings to common fittings without measuring or guessing.
• Extensive assortment: With 382 pieces across multiple cross sections and sizes from -006 to -327, the kit covers a wide range of on-the-job repair needs.
• FKM Viton material: Made from brown fluorocarbon 75A durometer, the rings resist oils, fuels, acids and alkalis for use in demanding chemical and automotive environments.
• Wide temperature range: Rated from about -15F (-26C) to +446F (+230C), the material suits high temperature hydraulic, engine and aircraft fuel applications.
• Organized storage case: A heavy duty case keeps each size separated and portable so technicians can carry the exact size needed and keep inventory visible.

Who It's For

The kit is aimed at professional mechanics, aviation maintenance personnel and serious DIYers who regularly service engines, hydraulic systems, plumbing fixtures or equipment that uses fluorocarbon-compatible seals. Anyone who values having a broad, aerospace-standard selection on hand will find this kit saves time and reduces downtime.

People with occasional light household sealing tasks may find the full kit more than they need and could choose a smaller assortment. Also, if a project needs a softer or different elastomer than FKM, this kit will not be suitable since the rings are specifically fluorocarbon 75A durometer.

Pros & Cons

Pros

• Large variety of sizes and quantities in a single, organized case for quick repairs.
• FKM material provides strong resistance to oil, fuel and many chemicals for demanding uses.
• Temperature rating makes it appropriate for high heat engine and hydraulic applications.

Cons

• Some customers report occasional edge cracking or thicker sections on a few rings, indicating variable durability in isolated pieces.
