R-Line NBR Lining Rubber

R-Line NBR Lining Rubber is a premium grade wear resistant Nitrile based rubber lining with a buffed back.


R-Line NBR is made from a premium Nitrile rubber compound and will display excellent resistance to oil and petroleum-based products including a range of fuels, greases, solvents and hydraulic fluids. It has low gas permeability and will display good water resistance. It is also resistant to vegetable oils, mineral oils and a range of aliphatic hydrocarbons.

R-Line NBR has excellent physical properties and will display good resistance to abrasion. It will also display good temperature resistance and moderate chemical resistance to some acids and alkalis.

R-Line NBR features a pre-buffed finish on one side to assist with adhesion when bonded to steel or rubber surfaces. It can be bonded using a wide range of Neoprene based rubber adhesives.


R-Line NBR Lining Rubber has been designed primarily for use as a wear protection lining system.

It is bonded to equipment to protect steel surfaces from abrasion.

It is predominantly used in Mineral processing, Agriculture and Manufacturing industries in applications which are subjected to a combination of abrasion and exposure to oils or oil based reagents.

It is typically used on the following: 

  • Tanks and pipework
  • Chemical pumps & impellors
  • Conveyor Pulleys
  • Transmission belt covers
  • Grain handling systems

R-Line NBR can also be used for any application which requires a flexible oil resistant rubber including:

  • Loading/discharge socks
  • Transfer and joining sleeves
  • Variety of sealing applications
