Is the STORZ firefighter union wrench, size 150/125, steel compatible with both 150 mm and 125 mm STORZ fire connections?

Yes. The STORZ firefighter union wrench, size 150/125, steel is designed to work with both 150 mm and 125 mm STORZ fire connections. Its dual-size designation (150/125) and steel construction indicate the wrench fits and engages the mating lugs for both diameters, providing the necessary strength and durability for joining or disconnecting 150 mm and 125 mm STORZ couplings.

Does the STORZ firefighter union wrench, size 150/125, steel fit different STORZ coupling standards and thread types?

The STORZ firefighter union wrench, size 150/125, steel is designed to engage the external lugs of STORZ couplings sized 150 and 125 (DN150/DN125). It fits standard STORZ lug geometry rather than specific thread types, because STORZ couplings are a non-threaded, sexless quarterâturn connection. Therefore the wrench will work across STORZ coupling standards that use the same lug dimensions for 150 and 125 sizes. It will not engage threaded pipe fittings or nonâSTORZ couplings with different lug shapes or nonstandard dimensions. Compatibility depends on the coupling following standard STORZ lug geometry for those sizes.

Can the STORZ firefighter union wrench, size 150/125, steel be used to tighten or loosen adapters and caps?

Yes. The STORZ firefighter union wrench, size 150/125, steel is designed specifically for STORZ fire connections of sizes 150 and 125. Made of steel, it provides the necessary strength and durability to engage the lugs and profiles of STORZ couplings, allowing you to tighten or loosen adapters and caps securely. Its size compatibility (150/125) ensures proper fit on those coupling dimensions, and the steel construction delivers the torque needed for routine assembly and disassembly under field conditions.
