Baso Y90HA-6721 Compression Coupling used to Control the Flow of Gas to a Pilot Burner.

• Material: Tip: Aluminum. Body: Brass.
• Maximum Temperature: Tip: 635F. Body: 750F.
• Ansi Code: Z21.20
• Orifice size: 0.021 inches
• Type of Gas: Natural and LP

The Y90 inlet fitting controls the flow of gas to a pilot
burner. The orifice hole size and counterbore/coining,
along with the applied gas pressure, determine flame
size and characteristics.
Pilot burner inlet fittings consist of an inlet tip
(containing the orifice holes) and a threaded inlet body
allowing connection of the pilot line. The orifice holes
are used to direct and control the flow of gas to a pilot
burner. The inlet fitting positions the orifice holes in
relation to the pilot burner
