Triangle Tube P3KITOR01 O-Ring Kit
**FINAL SALE - NO RETURNS OR EXCHANGES**
This O-ring replacement kit is designed specifically for Triangle Tube Phase III Indirect Fired Water Heaters across the TR, SMART, and HL series models. It provides the essential gasket needed to maintain a proper seal on the drywell assembly. During installation, apply firm but controlled pressure to secure the drywell without damaging the rubber O-ring—excessive force can compromise the seal and lead to leaks.
