also called coolant filler cap · expansion tank cap · radiator cap · sealing cap

A FILLER CAP CARRYING A CALIBRATED RELIEF VALVE, WHICH SEALS A LIQUID SYSTEM AND SETS THE PRESSURE IT RUNS AT BY BLOWING OFF ABOVE IT - a radiator cap, an expansion-tank cap, a coolant filler cap. UNSPSC 25174003 `Radiator caps`, in the cooling class 25.17.40 beside `Engine radiators` 25174002 and `Engine coolant` 25174004. THE CAP IS THE VALVE, AND THAT IS THE WHOLE REASON IT IS A CLASS. It looks like a lid and it is a pressure-control device: a cooling system boils at 100 C open and near 120 C at one bar, so the number stamped on the cap sets the engine's whole operating window, and fitting a 0.9 bar cap where a 1.4 was specified boils the engine. IT DECLARES `integral_valve` RATHER THAN MINTING A PRESSURE SLOT OF ITS OWN, AND THAT IS THE SHARPEST [A11] COLLAPSE IN THE BATCH. b153 built `integral_valve` for a filter's anti-drainback and bypass valves, cardinality many, each statement carrying its own `valve_opening_pressure` - and febi publishes a radiator cap's rating under the field name **`Opening Pressure: 1 bar`** (04496) and **`1.4 bar`** (01211), which is the pool's own property, in the pool's own words, on another house's sheet. A cap has TWO valves and the many-cardinality holds both: a pressure valve that blows off to the overflow bottle and a vacuum valve that lets coolant back as the engine cools. Motorad publishes the second as `Vented: Yes` and `Coolant Recovery System: Yes/No`, which are two readings of one fact - does this cap carry a vacuum-relief valve - and are therefore NOT minted as slots. SO THE PRESSURE FAMILY IS NOW THREE CLEAN CONCEPTS ACROSS THE POOL and no fourth was invented: what a PUMP DEVELOPS is `pump_pressure`, what a VESSEL OPERATES AT is `operating_pressure`, and what a VALVE OPENS AT is `valve_opening_pressure`. The queue's own note that `operating_pressure` is scoped to `MultiCooker` and would have to be re-declared or re-minted is answered: neither, because it was the wrong concept for a cap. THE OTHER SLOTS. `cap_release` because Motorad publishes `Type: Standard` against `Type: Safety Lever` as a named field with `Lever Type` and `Quick Pressure Release` beside it, and because a standard cap on a hot system throws boiling coolant at whoever opens it - the only safety fact in this batch. `filler_neck_diameter` and `filler_neck_depth` because Motorad publishes both as numbers (`Filler Neck Inside Diameter 38.86 mm`, `Filler Neck Depth 29.97 mm` on the T16) and because they are the two dimensions that decide whether a cap fits and seals: Stant sells the 10231 for `a 3/4 inch deep A size filler neck`, an A-size neck being one diameter with two depths, so the right diameter with the wrong depth screws on and does not seal. Neither is a fitment: both name a dimension of the sealing face in the hand, no vehicle and no maker, which is `thread_size`'s test [H4-f9]. THE SPINE CARRIES THE REST AND NOTHING WAS RE-MINTED [A11]: Gates publishes `Outer diameter [mm]: 45` and `Height [mm]: 20` for the RC133 straight into the spine's `diameter` and `height`; Motorad's `Material: Stainless Steel / Rubber` and `Color: Silver` are `material [many]` and `color`; `Weight: 64.6 g` is `net_weight`; and `Shape: Round` is the live `shape` - DECLARED ON THIS CLASS RATHER THAN ASSUMED [A-5], because `shape` was minted at b106 on `Dinnerware` and lives on six kinds but NOT on `Product`, so a class that merely claimed it would have left Motorad's own field unstateable. A zero-machinery cross-kind re-declaration, which `shape`'s own definition already invites. WHAT THIS CLASS CANNOT SAY, RECORDED RATHER THAN HIDDEN. Motorad publishes THREE pressure figures for one cap - `SAE Pressure Range (PSI): 14-18`, `Pressure Rating: 16.0 PSI` and `Maximum Pressure: 18 PSI` on the ST16 - and only the middle one has a home; a range and a ceiling are the standing bounds obligation, on a seventh trade. The same house publishes `Attachment Type: Cam-On`, how the cap locks to the neck, which no other maker prints and which is filed as an obligation rather than minted on one witness. And the trade cannot agree what to call the number at all: Stant heads it `Pressure Rating (PSI)`, Gates `Pressure` (printing 1.1 bar AND 16 psi as two rows of one field), Motorad `Pressure Rating`, febi `Opening Pressure` - four houses, four field names, one quantity, which is the strongest argument in this batch that the pool's job is a code and not a string [L10]. WHAT THE SOURCE MAY AND MAY NOT WITNESS. Habib's one row is `Radiator Cap (Kichuchu) 0.9`, whose note reads *Mifuniko ya rejeta ya Gari ndogo ndogo* - radiator covers for small cars. The `0.9` is the shop's own figure and it is a bar rating, which is the one specification anywhere in this vertical that Habib's sheet actually states; even so the differentiae stand on Motorad's own T16, ST16, T16R and T20R pages, on Gates' RC133 and RC255 records, on Stant's 10230 and 10231 records and on febi's 04496 and 01211.
