What material is the Gladiator hose liner made from?

• A. EPDM
• B. PVC
• C. Neoprene
• D. Nitrile rubber

Answer: (D)

Understanding which liner material resists hydrocarbon exposure is crucial. Nitrile rubber offers excellent resistance to fuels and oils, so the liner won’t swell, soften, or degrade when the hose handles gasoline or diesel, while still staying flexible and durable under typical use and temperature ranges.

Other materials have drawbacks in these conditions: EPDM is great with water and weathering but isn’t as resistant to hydrocarbons; PVC is cheaper and stiff, prone to cracking with flex and exposure; neoprene is decent but nitrile generally provides better oil and fuel resistance. So, nitrile rubber best meets the need for a hose liner that endures hydrocarbon exposure without sacrificing flexibility.
