Keep your Porter Cable finish nailer sealing properly, cycling smoothly, and working longer with the KT-PC-100 Reliability Provin Air Nailer O-Ring Kit. This kit is built as a high-performance replacement for worn OEM O-Rings in Porter Cable NS100 and NS150 finish nailers.
For repair shops, contractors, and maintenance users, this kit helps reduce air leaks, weak firing, poor cycling, and downtime caused by worn or damaged O-Rings. The O-Rings are color coded to make installation easier, helping save time during rebuilds and reducing the chance of installing the wrong seal.
Operating temperature: -40° to +225°F (–40° to +107°C)
The KT-PC-100 Reliability Provin O-Ring Kit includes replacement O-Rings for the Porter Cable NS100 and NS150 finish nailers. These seals are selected to provide reliable air sealing performance in pneumatic tool applications where repeated cycling, compressed air, and shop conditions can cause standard seals to wear over time.
This kit is designed to replace the O-Rings used throughout the tool and includes instructions with a schematic to help guide the repair process. Color-coded O-Rings make it easier to match seals during installation, which is a major benefit when servicing small pneumatic tools with multiple similar-looking O-Rings.
Chemical compatibility will depend on the exact O-Ring compound included in the kit, but pneumatic tool O-Rings are commonly selected for air tool service and light lubricant exposure.
- Excellent resistance to: compressed air, common pneumatic tool oils, light petroleum lubricants, and general shop use
- Limited capability with: aggressive solvents, strong cleaning chemicals, and unknown lubricants
- Not compatible with: harsh acids, strong oxidizers, and chemicals outside normal pneumatic tool service
