Reliability of a metal-to-metal mechanical fit between cup and level compensator or other mounting element
Captured O-Ring for superior vacuum seal
Precision machined barb design presses right into vacuum cup and seals tight
Quality Electroless Nickel Plated Brass for durability
The design of the Captured O-ring Barbed Fitting combines the reliable mechanical fit of a metal-to-metal connection with the unmatched static sealing qualities of an O-ring. Proper installation of the fitting allows the skirt around the O-ring to mechanically seat on the rim of the female thread, holding the fitting tight. A clean looking connection is achieved by concealing the high quality Buna-N O-ring from view inside the skirt of the fitting. The Buna-N O-ring is thus compressed, not pinched, within the fitting skirt ensuring a leak-proof fit even when mated with a less than perfect sealing surface. The mechanical fit keeps the fittings tight and retains its position even under constant vibration or movement of our SLSA Level Compensators. Our captured O-ring design eases installation and eliminates the need for replacement gaskets or washers as the seal is already in position. The seal is kept tight minimizing unnecessary vacuum loss.
