✅ Stainless steel housing resists rust in damp warehouse and retail environments

💡 When upgrading an automated fire sprinkler system, how do you match the right k-factor for steady water distribution?
The straight answer comes down to sizing your main feed pipe so your handy sprinkler delivers consistent pressure when the thermal sensor blows.
- Compare your building flow rates against the nozzle k-factor chart to stop dead zones from forming near distant ceiling tiles
- Leave enough clearance around the exposed glass bulb so rising hot air hits the calibration point directly without deflecting off rafters
- Purge trapped air from the branch lines after tightening the fitting to guarantee smooth liquid travel through every joint
