Brass Compression Sleeves 15 Pack
These 5/16 inch brass compression sleeves come in a pack of 15. They are designed for sealing tubing connections in air compressor and vacuum pump systems. The brass construction resists corrosion during fluid transfer applications.
For Air System Repairs
Suitable for technicians and DIY users maintaining pneumatic lines or hydraulic circuits that accept 5/16 inch fittings. Not suited for buyers who need a different tubing diameter or a larger quantity than 15 pieces.
5/16 Inch Size
The critical specification is the 5/16 inch nominal size which must match the tubing outside diameter exactly. Verify this dimension against your system requirements before ordering.

Questions about this item
Will the 5/16" brass sleeves work with my existing 5/16" copper or aluminium tubing?
Yes, the 5/16" size matches standard tubing of that outer diameter, and brass compression sleeves are compatible with copper, aluminium and plastic lines used in air and fluid systems.
How can I verify a leak-free seal once the sleeves are installed?
Pressurise the line to its working pressure and apply soapy water to each joint; bubbles indicate a leak, while a dry joint confirms the ferrule has seated correctly.
Does the 15-pack include nuts or inserts, or must they be purchased separately?
The pack contains fifteen brass compression sleeves only; matching compression nuts and any required tube inserts are sold separately.
