NACOL'S bladder is moulded in one piece. One piece construction withstands pressure better, increasing bladder life and decreasing accumulator failure.

Most competitor's large accumulator bladders are made of three or four pieces that are vulcanized together. Often pin hole leaks develop at the seams, causing loss of the entire nitrogen charge. The entire bladder can even separate at these seams. Most accumulator users are familiar with this type of failure.

The NACOL bladder is moulded in one piece to prevent seam leakage and bladder failure at the seams. In some sizes the very bottom of the bladder is moulded as a second piece in order to make the bottom much thicker. By eliminating the three or four piece bladder, NACOL has eliminated a major cause of accumulator failure
