Lead-Free Tinning Flux Paste

Oatey 30372 is an 8 oz lead-free flux paste formulated for plumbing and potable water systems. It meets NSF 61 standards and suits brass, copper, galvanised iron, tin or copper-coated metals, and zinc. The petroleum base cleans effectively during soldering and will not turn copper piping green.

8 oz Can Capacity and 464 °F Limit

The 8 oz container provides enough flux for large-diameter copper piping jobs and multiple joint preparations. Active performance extends up to 464 °F, covering typical lead-free solder melting ranges. Beyond that temperature the flux breaks down and no longer protects the joint from oxidation.

Flux Remover Clean-Up Requirement

Residue must be removed with a dedicated flux remover after soldering is complete. The paste formulation clings well to vertical pipe runs during application, but the petroleum base does not wash away with water alone. Proper cleaning ensures code-compliant potable water installations.

Questions about this item

Will the 8 oz can of lead-free flux paste work with my older copper and brass plumbing fittings?

Yes, the paste is formulated for brass, copper, galvanized iron, tin, copper-coated metals, and zinc, making it compatible with common older plumbing materials.

How can I verify the flux is active at the correct temperature during a joint?

The flux has a maximum active temperature of 464 degrees F, so it will remain active through the typical lead-free solder melting range.

Does the 8 oz can include a brush or do I need to buy a flux remover separately for cleanup?

The container is a paste can only; application tools and flux remover for cleanup are sold separately.
