Workshop Warehouse Grease Nipples Straight – Imperial Size 1/4in. UNF (GN3)

Description

Genuine Workshop Warehouse · Part no. GN3

Workshop Warehouse straight grease nipples with a 1/4in. UNF imperial thread, the size found on many older British cars, trailers and farm machines. Each one screws into a greasing point so a grease gun can push fresh grease into the bearing or joint, and a spring-loaded ball closes behind it to keep dirt out.

Good to know

• How do I know my nipple is 1/4in. UNF? Take the old one out and compare threads with a gauge or a known nipple; UNF looks very like metric M6, and forcing the wrong one strips the hole.
• Why choose straight rather than angled? A straight nipple suits points where the grease gun can come at it head-on; if a chassis rail or wheel is in the way, an angled nipple is easier to reach.
• How do I fit it? Clean the hole, start the thread by hand, then nip it up gently with a small spanner; the thread is small and snaps if overtightened.

Which one?

Not sure of the thread? The Workshop Warehouse Grease Nipples – Metric & Imperial (AB46) covers both. For 1/8in. BSP, the Workshop Warehouse straight nipples (GN1).
