got a drain port that’s 1/4 NPTF female, is this the right drain cock for that?
Answer by: Customer Support on Oct 29, 2025, 9:49 AM
Fit comes down to the connection type and size. This one is a 0.25 inch NPTF female end, made as an external drain cock style, so it matches a 1/4 NPTF female requirement.

what's the lowest temp this drain cock can handle? got some equipment sitting outside through winter and need to know if it'll hold up
Answer by: Customer Support on Jul 30, 2025, 3:18 PM
Rated down to negative 65 degrees, so cold weather operation isn't going to be a problem. Brass construction combined with the Dura-Kote corrosion-resistant plating means it holds up well even when conditions get rough over a long season.
