Flexible oil line hose, approx 900mm long
1/4 inch male BSP elbow at one end (this usually suits Riello central heating oil burners).
3/8 inch female BSP connector at the other.
Look at our oil line nipples for suitable connectors (this oil line has special cone shaped ends, which need a face to face joint).
BSP (British Standard Pipe Thread) sizes don’t match up with what you would measure using a ruler. Have a look at the BSPT link at the bottom of this page for more information about how plumbing threads are measured.
