Buying Guide

Leaks and pressure loss can ruin your cleaning flow. The right sealing washers keep your gear dripping-free and powerful.

  • Material Matters: Viton FKM handles extreme heat (up to 400°F) and harsh chemicals. NBR rubber resists oils and stays flexible in cold or hot settings.
  • Size Variety: Quick couplers need 1/4″ or 3/8″ O-rings. Multi-size kits (M6-M30 or 6 sizes) cover pumps, hoses, and nozzles to avoid leaks everywhere.
  • Temp & Chemical Resistance: Look for high-temp ratings (like -22°F to 248°F) and corrosion-proof rubber. These handle detergents, oils, and weather extremes.
  • Model-Specific Kits: Simpson users need pre-fit seals (like 7105742 kits) to match pump numbers. Saves time and ensures a perfect fit.
  • Durability Boosters: Thick rubber, reinforced fibers, or stainless steel filters fight wear. Tear-resistant designs last longer under pressure.
  • Easy Installation: Pre-cut sizes, color-coded kits, or storage cases make swaps quick. Some kits include lubricant or tools for smooth fixes.
  • Quantity Counts: 100-packs (like orange Buna-N rings) or 48-piece sets give spares. Avoid mid-job runs to the store.
  • Seal Type: Bonded washers grip metal parts. Multi-seal kits include low/high-pressure rings and fiber backing for full pump coverage.

Pick the right washer, and your pressure washer stays leak-free, strong, and ready for any task.
