Made in Kevlar for longer life.
This is the regular length 50mm long bypass hose used on all Mini's from 1959 except 1275cc inc Cooper S (AEG484) until the factory introduced the longer head bypass tube (12A2075) and shorter hose (GZA2086) to enable changing the hose without removing the cylinder head.
GZA2086 was 42.5mm so you will have to shorten this hose by up to nearly 10mm to fit the later type bypass hose adaptor 12A2075.
Recommend: 1 x GZA2083 per Mini.
For bypass adaptor tube, see 12A2075
