HENGSEN Replacement Caps for Air Conditioning Service Valves
Description
These HENGSEN replacement valve caps are available for matching air conditioning service valves. They provide a replacement for a missing or damaged cap and cover the valve access area.
Four fitment options are listed: a shared cap for matching 1/4" and 3/8" valves, plus separate options for 1/2", 5/8" and 3/4" valves.
The size labels refer to the associated valve connection size, not the cap’s thread diameter. Match the replacement cap to the original valve’s thread and seating dimensions before ordering.

Selection Guide
Use the valve connection size to identify the listed cap option, then compare the replacement with the original cap’s thread diameter, pitch, depth and seating arrangement.
The shared 1/4"–3/8" option applies to the matching valves in this range. It does not establish universal compatibility with every valve of those pipe sizes.
