In such a place, use of flame resistant fittings (KR/KRM series) and flame resistant tubing (TRS/TRB series) are recommended. 7. Do not use in an environment where the product is directly exposed to cutting oil, lubricant, coolant oil, etc. Please contact SMC if using for an environment exposed to cutting oil, lubricant or coolant oil, etc. 8.
Using other fittings or tubing may cause damage to the system and products. wFlame resistant fittings (Series KR/KRM) and tubing (Series TRS/TRB) are recommended for use in spatter applications. Fire may occur because of spattering. eDo not use fittings and tubing where they are directly in contact with cutting oil, lubrication or coolant.
