About 231209
231209 is a large needle-type grease zerk with .250-28 thread. The "large needle" designation indicates that this fitting uses a larger-diameter internal check ball/needle assembly than a standard Alemite-style zerk, allowing higher grease flow volume per pump stroke. This fitting is described as commonly used on CV shafts (constant-velocity driveshafts) where grease distribution to a larger ball assembly benefits from higher flow.
- Thread: .250-28
- Hex: 0.312"
- Overall Length: 0.406"
- Style: Large needle type
- Common use: CV shafts
The 0.406" overall length is shorter than the standard straight zerks (0.54"-0.78"), making this a low-profile fitting that minimizes projection above the yoke or shaft face. When a standard grease gun coupler does not seal well on a CV shaft grease port, changing to a large-needle fitting can improve grease delivery by reducing back-pressure at the check valve.
See all CV joint kits for CV shaft components requiring lube fittings.
