❓ Frequently Asked Questions (FAQ)
Q: Is this adapter universal?
✅ Yes, it’s designed to fit any system using 1/8" NPT oil and 1/4" NPT air intake fittings.
Q: What material is it made from?
✅ It’s machined from solid brass, ensuring durability and corrosion resistance.
Q: Can this be reused after disassembly?
✅ Yes, with proper thread sealing (PTFE tape or compound), it can be reused multiple times.
Q: How do I know if my old adapter needs replacement?
✅ Look for leaks, stripped threads, corrosion, or poor sealing at the connections.
Q: Is thread sealant required during installation?
✅ Yes, PTFE tape or a liquid thread sealant is recommended for a secure, leak-free seal.
Q: What systems is this most commonly used on?
✅ It’s widely used in oil burners, waste oil burners, and siphon nozzle assemblies.
Q: Does it affect burner efficiency?
✅ Yes — a failing or leaking adapter can cause poor atomization, inconsistent ignition, and efficiency loss.
Q: Is it resistant to heat and fuel exposure?
✅ Absolutely. Brass construction ensures it withstands high temperatures and long-term oil exposure.
