Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.
Sleeves for Compression Fittings for Copper Tubing

- For Use With: Air, Cutting Oil, Fuel Oil, Hydraulic Fluid, Mineral Oil, Water
- Temperature Range:
Inch: -65° to 200° F
Metric: -40° to 250° F - Tubing:
Inch: Use with firm or hard (Durometer 1A-95A) nylon plastic, polyethylene plastic, polypropylene plastic, polyurethane rubber, or copper
Metric: Use with copper - Specifications Met: UL listed, except for metric fittings
