K5.6 and K8.0 heads with selected temperature and pressure ratings
We supply upright fire sprinklers in K5.6 and K8.0 catalog families for distributors and fire-protection projects. The deflector sits above the frame in the installed upright position. Each quoted head keeps its K-factor, response classification, temperature rating, connection and required product approval together under one model reference.
| Orientation | Upright, with the deflector above the frame |
|---|---|
| Catalog K-factor | K5.6 / K8.0 (gpm/√psi); K80 / K115 (L/min/√bar) |
| Temperature | Six published nominal temperature selections below |
| K5.6 pressure options | 250 or 300 psi selected model series |
| K8.0 pressure options | 175 or 300 psi selected model series |
| Finish | Brass or chrome-plated catalog options |
| Model identity | K-factor, response, coverage, thread and approval record selected together |
The temperature rows are published for both K-factor families. Pressure options remain separated by family and selected model.
| Nominal rating (°F) | Catalog rating (°C) | K5.6 model pressures (psi) | K8.0 model pressures (psi) |
|---|---|---|---|
| 135 | 57 | 250 / 300 | 175 / 300 |
| 155 | 68 | 250 / 300 | 175 / 300 |
| 175 | 79 | 250 / 300 | 175 / 300 |
| 200 | 93 | 250 / 300 | 175 / 300 |
| 286 | 141 | 250 / 300 | 175 / 300 |
| 360 | 182 | 250 / 300 | 175 / 300 |

Published upright-head catalog temperature selections. The Fahrenheit/Celsius pairs retain their nominal product designations. The selected model record identifies its actual pressure rating, response and coverage classification, connection and approved application.
K-factor describes the discharge relationship. The selected model’s response classification and coverage designation identify different performance characteristics. Replacement schedules retain all three entries together so the purchased head matches the specified sprinkler.
UL 199 addresses automatic sprinklers for fire-protection service. A required listing record covers the actual manufacturer and model. The project’s adopted installation specification, including its applicable NFPA 13 requirements, determines the accepted arrangement and design duty.
The specified head temperature is selected for the local ambient conditions and project requirements. Our order line retains the complete temperature designation alongside K-factor and finish, keeping similar-looking heads identifiable during receiving.
The frame supports a deflector above the outlet. The selected installation detail fixes its orientation, location and clearance from nearby obstructions. The model reference carries that arrangement into the supply schedule.
The chosen head drawing identifies the inlet thread standard, nominal size and approved installation engagement. Matching those details to the branch fitting preserves the intended joint and head position.
Brass and chrome-plated options retain their own model and finish identification. Handling protects the thermal element, frame and deflector; finished heads stay in their protective packaging until installation under the selected instructions.
A project can require several temperature or K-factor selections. The takeoff groups identical models while preserving room or location references, making each delivered carton traceable to its specified head selection.
The existing head’s model reference and project specification establish response, coverage, K-factor and temperature. We quote the matching selected configuration with its connection and required approval evidence.
Receiving checks connect the selected model and temperature marking to its carton and order line. Response, K-factor, finish and required approval records stay under that same identity.
The delivered condition is checked for visible damage to the frame, deflector and thermal element. Protective packaging keeps those features clear of contact with adjacent heads and loose hardware.
The inlet condition and selected connection are checked against the order. Required product documents and installation information follow the exact head model and supplied quantity.
Our offer separates temperature, K-factor, finish and connection selections. The head quantity, required documents and packing basis belong to that identified model.
Individual head protection keeps deflectors and thermal elements from carrying packing pressure. Carton groups separate the selected temperature and model references.
Project spare-head quantities and any specified model-matched wrench have their own order entries. The receiving list distinguishes those items from the installed-head takeoff.
The rating identifies the selected thermal element’s nominal designation. The actual response also depends on the head’s response classification and exposure conditions. The project selects the complete model for its location and operating environment.
A replacement follows the specified orientation, coverage and model requirements as well as K-factor. The upright and pendent installation arrangements retain their own approved product and clearance details.
Use the wrench specified for the selected model and its wrenching surfaces. We can itemize that model-matched tool separately from the head quantity, keeping its reference visible on the quotation.
Group spares by the actual installed model, K-factor, response, temperature and connection. The project’s spare-head schedule determines the quantities, while our packing list keeps the supplied selections identifiable.
Finish describes one part of the selection. A replacement is identified through its model, K-factor, response, coverage, temperature and connection, using the installed record or legible product markings.
Yes. Each temperature and model selection has a separate line, quantity and carton identity. The consolidated packing list retains those distinctions for project allocation and distributor receiving.
Other items in the same product category.
Send the K-factor, temperature selections, model or response/coverage specification, connection and quantities. Add the required approval records and destination. We return identified head selections, separately counted spares and wholesale packing terms.
