When looking for tubing that won’t let you down for sampling look no further than Oil Analysis Laboratories. Unlike cheaper aquarium type tubings available from other labs that melt and bend at equipment operating temperatures and make taking samples from dipsticks almost impossible, our tubing is made from extra durable high pressure hose that stays rigid when trying to direct it down a sampling port to take a sample. This means whatever you want to sample via your vacuum pump you will have the right tubing for the job.
