Description
Overview:
The Brass Stepped Olive 5/16" is a small, precision-machined ring used in compression fittings to create a reliable metal-to-metal seal on tube connections. Manufactured from solid brass for strength and corrosion resistance, it suits 5/16 inch (7.94 mm) outside diameter copper or brass tube commonly found in plumbing, heating, and light industrial pipework. The stepped profile helps the olive centre itself and bite evenly, improving sealing performance while reducing the risk of over-compression. This makes it a practical choice for water, air, and light oil service in workshops, construction sites, and garden machinery setups where robust, leak-tight joints are required. A straightforward, serviceable solution for repairs or new installations. Manufacturer Part Number (MPN): 615 142.
Key Features:
- Durable solid brass construction for long service life and corrosion resistance
- Stepped design promotes even compression and a more consistent seal
- Sized for 5/16" (7.94 mm) OD tube for a snug, leak-resistant fit
- Compatible with standard 5/16" compression nuts and fittings used in UK plumbing
- Suitable for copper and brass tube; can be used with plastic tube when the correct support insert is specified by the tube manufacturer
- Forms a metal-to-metal compression seal, avoiding reliance on thread sealants at the olive joint
- Smooth internal finish helps protect the tube surface during tightening
- Compact ring form factor for use in tight spaces and confined assemblies
- Stable sealing performance for water, air, and light oil duties in low to medium pressure systems
- Clearly identified as MPN 615 142 for easy reordering and stock control
Typical Applications:
Used to seal 5/16" (7.94 mm) compression joints in domestic and commercial plumbing, heating microbore circuits, irrigation and sprinkler feeds, workshop air lines, coolant loops on machinery, and light oil service lines. Common in plant maintenance, agricultural equipment servicing, and garden machinery setups where dependable, serviceable compression fittings are preferred over soldered joints.
