Canarm - Brass Fitting and Nut for Heated Waterer (H0524)

The Canarm H0524 brass fitting and nut creates a secure, leak-proof connection between the waterer's water supply line and the fill valve or hose. It typically serves as a compression or union fitting that allows the supply hose (H0-G4958) or supply pipe to be connected to the waterer without soldering or special tools.

The nut component provides the clamping force that seals the fitting — tighten by hand first, then with a wrench to 1/4 turn past hand-tight. Avoid overtightening, which can crack the fitting body or distort the sealing surfaces.

As with all Canarm brass plumbing components, use Teflon thread tape on all threaded connections and inspect annually for corrosion or mineral buildup.

Yes — Canarm brass fittings can be used with PEX tubing, which is the preferred supply line material for heated waterer installations in cold climates. PEX (cross-linked polyethylene) is flexible, freeze-resistant, and easy to route through barn structures.

For PEX connections to brass NPT fittings, you will need a PEX-to-NPT adapter (either crimp or push-to-connect style), available at plumbing supply stores. The crimped barb style is generally more reliable for underground or wall-run supply lines; push-to-connect adapters are convenient for accessible connections.

Always insulate PEX supply lines where they run through unheated spaces — even PEX can freeze and split if water is not moving and temperatures drop below -10°C for extended periods.
