Lever-lock pattern P — seals gaskets.
Lever-lock pattern P — seals gaskets. The10 bar maximum working pressure applies to the galvanized mild-steel pattern P construction shown; temperature and medium conditions require confirmation. KVG/KVS/KVF/KMS/KMG/KMF/KXV/KXM and QC references identify configurations, not complete size-specific ordering codes. Head sizes and dimensional reference pairs are nominal designations, not measured bore/OD.

Claw coupling EU — seals gaskets.
Claw coupling EU — seals gaskets. EU and US claw interfaces must not be treated as interchangeable. Use the exact claw count, material, end connection and locking arrangement. For US, 16 bar is carried only on the two-claw threaded sections; no16 bar rating is assigned here to hosetails or four-claw variants. No generic temperature or torque value is inferred.

Brass water-service claw cap and gasket.
Brass water-service claw cap and gasket. Use only with the matching brass water-service claw interface. Cap or gasket fit does not establish pressure-closure suitability for a different coupling pattern.
| Part code | Component | Fit |
|---|---|---|
| RWGC025 | Rubber gasket | One size fits the brass water-service claw range |
| GCB025 | Blind end cap | One size fits the brass water-service claw range |
Symmetrical coupling replacement front seals.
Symmetrical coupling replacement front seals. Match lug designation, claw count, nominal end size and material; nominal hose size alone does not establish compatibility. Lug designations are retained as identifiers; no unit is guessed for an unlabelled lug number. Pressure requires exact construction confirmation: an aluminium6–8 bar note and a broader16 bar family claim must not be flattened into one rating.
