Safety Vent

All NACOL accumulators have a safety vent. This eliminates the possibility of accidentally removing the top cover while the accumulator is fully charged. As the top cover is un-threaded, it opens the vent hole and the nitrogen is discharged before the cover becomes a projectile.

One Piece Pleated Bladder

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. ...
