Product Details

The S.U.R.&R. Auto HOR430 is a 50-piece pack of 10.82 x 1.78mm HNBR (Hydrogenated Nitrile Butadiene Rubber) O-rings engineered for automotive A/C, refrigerant, and fluid system sealing applications. This size corresponds to the common 7/16" x 1/16" SAE equivalent, making it a frequently needed replacement in R-12 and R-134a air conditioning systems.

HNBR compound offers significant performance advantages over standard NBR O-rings, delivering superior resistance to heat, chemicals, and mechanical wear — ideal for the demanding conditions found in automotive HVAC and fluid circuits.

Key Features:

  • Material: Highly Saturated Nitrile (HNBR) rubber, 70 Shore A hardness
  • Dimensions: 10.82mm inner diameter x 1.78mm cross-section
  • SAE Equivalent: 7/16" x 1/16"
  • Quantity: 50 O-rings per bag
  • Withstands wider temperature variations than standard NBR O-rings (-25°C to 150°C operating range)
  • Greater chemical resistance — compatible with most automotive fluids and refrigerants including R-12 and R-134a
  • Superior abrasion resistance for high-dynamic load applications
  • Replaces worn or damaged O-rings to eliminate refrigerant and fluid leaks

Sold in a convenient 50-piece bag, the HOR430 is also a direct replacement for this size as found in S.U.R.&R.'s HOR350 HNBR O-ring assortment kit.

Someone picked up the phone which is cool

I was very satisfied with the item we purchased and delivery time. The only thing I wish we could of done was add another item to our shipment before it was shipped. We I called customer service but was told that could not be done.

Great and trustworthy checkout process

My experience was better than expected. Shipping was fast and knowledgeable.

Good company to work with.

Fast shipping!
