Fitting O-rings are small but critical sealing rings used in various boiler and burner connections. These O-rings create a tight seal between fitting components, preventing leaks of water or gas. Made from resilient materials, they withstand high temperatures and pressure fluctuations. Ideal for maintenance and repair, these O-rings are a common spare part for ensuring leak-free operation in heating equipment. Keep a set on hand for quick replacements during service.
