Description
Replacement 109 O-Rings for Core Removal Tools (10 Pack)
Don't bin a perfectly good core removal tool (CRT) just because of a blown seal. When you're pulling a deep vacuum or holding pressure on site, a leaky tool is a massive headache. Grab a packet of these replacement Size 109 neoprene O-rings and get your gear back to sealing tight. It’s a cheap, dead-simple fix that keeps your tools on the job and out of the trash.
Key Features
- CRT Main Body Repair: Provides all the necessary O-rings to repair the main body of standard core removal tools. (Note: These do not replace the internal chuck O-rings that grab the core stem).
- Tough Neoprene Build: Made from durable black neoprene to handle harsh refrigerant oils and workshop abuse.
- Exact Sizing: Industry standard Size 109 O-Ring.
Tradie Tip: Always keep a spare packet of O-rings in your van. Seals often get chewed up from over-tightening or contaminated refrigerant. A two-minute swap on site saves you from a frustrating vacuum leak right when you need to pack up and head home.
