Front and Back Sleeves for Yor-Lok Fittings for Stainless Steel Tubing
- For Use With: Air, Cutting Oil, Fuel Oil, Gasoline, Hydraulic Fluid, Mineral Oil, Natural Gas, Steam, Water
- Temperature Range: -420° to 1200° F
- Tubing: Use with seamless or welded 304/304L or 316/316L stainless steel that meets ASTM A213, ASTM A249, or ASTM A269
- Compatible With: Let-Lok, Parker A-Lok, Swagelok®
Couple these sleeves with Yor-Lok nuts and fittings to create an extra-strong seal on stainless steel tubing. Sleeves are 316 stainless steel for excellent corrosion resistance. They are also known as ferrules.
Sleeves with a dispenser come with 10 sets of front and back sleeves. Rather than stacking sleeves in your hand, the dispenser stages them for quick alignment with your Yor-Lok fitting. Insert the dispenser into the fitting, then slide the sleeves into place.
