Grease Nipple for Springs – Couplings
Grease Nipples to suit M16 and M18 shackle bolts installed in Rocker Roller Springs.
Button head spring nipples are available with a choice of 3 angles; they are straight, 45 degrees and 90 degrees.
Override coupling has 2 nipples installed at the front and rear mounting points. These nipples allow grease to lubricate moving parts within the coupling.
The thread size for rocker roller springs is M10, whereas the thread size of the coupling is 1/8″ BSP.
Also, nipples suit Al-ko couplings and shackle bolts as follows.
- M16 Greasable Bolts
- M18 Greasable Bolts
- Rocker Roller Springs
- Standard 2t Override Couplings
- 2t Offroad Override Coupling
Sorry, we cannot provide specifications to suit other brands of couplings or springs.
It is important to note that when installing the bolt, first remove the nipple. Hammers easily damage nipples.
Any commercial petroleum-based grease is suitable for use greasing shackle pins and couplings.
Tandem Suspension has three greasing points on each side. Two spring shackles and the centre pivot of the rocking beam.
Couplings especially override couplings become unfit due to a lack of lubrication on critical wearing parts. A combination of vibration and actuation requires lubrication of all grease nipples in a trailer or caravan installation.
Claims on damaged grease nipples must be lodged within 7 days of receipt of goods.
