The coupling also has a safety ring mounted on the locking cap to prevent inadvertent disconnections. The spikes come in standard or anti-twist versions; the latter contribute to reducing spherical marks that, over time, deteriorate the quality of the product and reduce its useful life. The plastic dust cap comes standard in couplings and nipples, which are available in their fixed or rotating version. Before being delivered to the customer, each coupling and nipple is individually checked at maximum working pressure. This series makes it possible to attach pumps and accessories more quickly, safely and comfortably, even under extreme pressures. Series 135 is especially recommended for bearing pullers, nut breakers, and hydraulic testing facilities.
