This Lochinvar orifice holder is a crucial component designed for Polaris LP (Liquid Propane) systems. The product, also known as an 'K' orifice holder, is engineered to securely hold the orifice, a small opening through which the LP gas flows into the burner. The holder ensures that the orifice is correctly positioned to facilitate optimal gas flow and combustion. Made from durable materials, it is designed to withstand high temperatures and pressures typically associated with LP systems. This Lochinvar orifice holder is compatible with specific models of Polaris LP systems and aids in maintaining their efficient operation.
