Canarm - Brass Elbow for Heated Waterer (H0523)

Canarm specifies brass fittings (H0523 elbow) for waterer plumbing connections rather than plastic for several important reasons:

• Temperature cycling resistance: Waterer supply lines go through hundreds of freeze-thaw cycles over their service life. Brass expands and contracts without cracking; plastic fittings can fail at low temperatures or become brittle over time.
• Thread integrity: Brass threads maintain their precision over many tightening/loosening cycles. Plastic threads strip easily, especially in cold weather when plastic is less pliable.
• Pressure resistance: Farm water supply pressure can fluctuate widely. Brass handles pressure spikes that can crack plastic bodies.
• Longevity: A quality brass fitting properly installed with thread tape will typically outlast the waterer itself. Plastic fittings in the same application may require replacement every 3–5 years.

The Canarm H0523 brass elbow uses standard NPT (National Pipe Thread) threading, compatible with standard North American plumbing fittings. The specific thread size (typically 3/8" or 1/2" NPT) should be confirmed against your waterer's supply inlet before ordering.

When installing brass fittings on a Canarm waterer, always use Teflon thread tape (PTFE tape) wrapped 2–3 times clockwise around the male threads before installation. This ensures a watertight seal and makes future disassembly easier. Do not overtighten — brass threads can gall if excessive torque is applied.

If you are unsure of the thread size needed, bring the old fitting or the waterer's inlet fitting to any plumbing or farm supply store to find a match.
