Parker 8 ALOK-316-SET A-LOK Ferrule Set, 1/2″ Tube OD, 316 SS

Keep your A-LOK connections sealing like new with this genuine Parker ferrule set. The 8 ALOK-316-SET pairs the front ferrule and back ferrule you need to make up or rebuild a 1/2 inch A-LOK two-ferrule tube fitting. When you service a line, replace a worn ferrule, or complete a new assembly, these matched components restore the gas-tight, leak-free seal your instrument systems depend on. Parker machines them from chemically hardened 316 stainless steel, so they bite harder, resist corrosion better, and outlast untreated stainless. The front ferrule seals against the fitting body while the back ferrule grips the tube, and together they give you A-LOK's proven two-stage hold under pressure and vibration. Use genuine Parker ferrules to protect the integrity of your connection and your warranty. Each set ships on a holder that simplifies ordering, stocking, and assembling, so your techs grab the right parts fast. Do not risk a critical seal on mismatched components. Spec the real thing.
