Can the Adaptor for 1/4"- 1/8" pressure gauge withstand common hydraulic fluids without NBR degradation?

Adaptor for 1/4"- 1/8" pressure gauge Format uses a carbon steel body with NBR (nitrile) o-ring sealing. NBR is generally resistant to many common hydraulic fluids such as petroleum-based hydraulic oils, mineral oils, and some lubricating oils at typical operating temperatures, so in those systems the Adaptor should perform satisfactorily without rapid NBR degradation. However, NBR has limited resistance to certain fluids: it degrades with prolonged exposure to ketones, some esters, phosphate esters (some fireâresistant hydraulic fluids), turbo oils, certain alcohols, and fluids with high aromatic or chlorinated solvent content. Elevated temperatures, ozone, and hydraulic fluids containing aggressive additives can also shorten NBR service life. Carbon steel is compatible with standard hydraulic oils but will corrode in presence of water, certain glycolâbased fluids, or if not properly protected. Conclusion: If your hydraulic system uses standard petroleum/mineralâbased hydraulic oils at normal temperatures, the Adaptor for 1/4"- 1/8" pressure gauge Format with NBR sealing should withstand exposure without NBR degradation. For phosphateâester fluids, waterâglycol, synthetic esters, or other nonâpetroleum fluids, verify chemical compatibility or choose an adaptor with a different elastomer (e.g., FKM/Viton or EPDM) and appropriate plating/corrosion protection for the carbon steel.

Is the Adaptor for 1/4"- 1/8" pressure gauge compatible with high-temperature applications above 100Â°C?

Adaptor for 1/4"- 1/8" pressure gauge Format made of carbon steel with an NBR (nitrile rubber) O-ring is generally not recommended for sustained high-temperature applications above 100Â°C. Carbon steel can withstand elevated temperatures, but NBR has a typical continuous service limit around 100Â°C and will degrade, harden or lose sealing performance if exposed above that. For reliable sealing over 100Â°C choose an adaptor using a high-temperature elastomer (e.g., Viton/FKM, Silicone, or PTFE seals) or confirm the specific NBR grade and supplier-rated temperature range before use.

Does the Adaptor for 1/4"- 1/8" pressure gauge include a spare NBR o-ring for replacement?

Adaptor for 1/4"- 1/8" pressure gauge Format does not explicitly state that a spare NBR o-ring is included. The description lists an o-ring and NBR sealing material, which indicates the adaptor uses an NBR o-ring for sealing, but there is no mention of an extra or replacement o-ring being supplied. If you need a spare, consider contacting the seller or supplier to confirm or ordering a replacement NBR o-ring separately.
