Steck (Test 10) & HSP (5/8" BSF) Test Points
Steck (or Test 10) push-in test points are sometimes found on older systems or where space is very limited to fit a test point or hose. The push-in probe has no thread and is retained by a clip.
HSP-style test points for connection to 5/8" BSF microbore or gauge connections. This product has ball-sealing technology, so it does not carry the Minimess® lifetime leak-free guarantee.
