How Storz Couplings Work
Two identical coupling heads engage at the lugs and lock with a short turn. Because there is no male or female mating half at the Storz face, hose sections can be connected quickly in either direction.

Storz Coupling FAQ
Quick answers for product identification, compatibility and ordering.
How do I identify the correct Storz coupling size?
Measure the clear distance between the two locking lugs, then provide the hose inside diameter or thread size. A product photo and dimensions help confirm compatibility.
Which Storz end connections are available?
Common configurations include hose end, female thread end, male thread end, blind cap, 4-inch mining hose coupling and 6-inch mining hose coupling.
Which seal material should I select?
NBR is the standard choice for general water service. EPDM or FKM seals can be quoted when temperature or fluid compatibility requires them.
Can MCHEN match an existing coupling?
Yes. Send a clear photo, lug spacing, hose or thread size, working pressure and required quantity for a compatibility review.
