York S1-025-27727-002 Temp Control The center 1/2" NPT (MPT)

The center 1/2" NPT (MPT) connection features dryseal taper threads to minimize potential leak paths and provide extra clearance for tightening flare nuts

Industrial Durability: Resilient construction prevents pinching and deformation under the high compression loads of hand hole cover bolts

Key Benefits for the Contractor Enhanced Durability: The cadmium-plated steel construction prevents oxidation and premature wear in high-humidity duct environments
