A 200-piece NBR O-ring kit with 1.9 mm, 2.4 mm and 3.1 mm cross-sections for sealing internal power-cable connections

  • 200-piece kit keeps spare seals on hand for maintenance
  • Nitrile rubber resists oil and fuel in PC cooling loops
  • Three thicknesses (1.9, 2.4, 3.1 mm) cover common fitting sizes
  • New condition ensures clean, uncontaminated rings for reliable seals

NBR O-ring kit with three thicknesses

This 200-piece kit supplies nitrile rubber O-rings in 1.9 mm, 2.4 mm and 3.1 mm cross-sections. The assortment covers common internal power cable sealing tasks in a single box. Each ring is moulded from NBR for resistance to oil and fuel contact. Builders can address multiple fitting sizes without sourcing separate packs.

Assorted cross-sections reduce spare-parts inventory

Having three thicknesses in one package means fewer part numbers to track and less chance of ordering the wrong size. The 200-piece count provides enough rings for several builds or maintenance sessions. NBR material suits typical PC liquid-cooling and cable-gland applications. Users who need metric ID standards or larger diameters will need a different kit.

Questions about this item

When will the 1.9 mm, 2.4 mm or 3.1 mm NBR O-rings need replacement?

NBR O-rings should be inspected regularly and replaced when they show cracking, hardening or permanent deformation from heat and chemical exposure.

What is the first limit reached when the kit is used continuously in a sealing application?

The 200-piece assortment provides finite quantities of each 1.9 mm, 2.4 mm and 3.1 mm size, so the first limit is running out of the required diameter.
