Fire Sprinkler Heads

Fire sprinkler heads come in a wide range of colors, temperatures, orientations, and K-factor types, each designed for specific applications. It's essential to choose the correct sprinkler head for your system, as they cannot be mixed or substituted. If you need to replace an existing sprinkler head, it must be replaced with the exact model or an approved replacement from the manufacturer. If you're unsure about which head you have, we're here to help. Simply contact us with a photo of your sprinkler head, ensuring the stamped identification number is visible, and we will assist in identifying the correct replacement. Reach out to us via call, chat, or email at sales@bulkindustries.com with your photos, and we'll match the exact head you need.Ā
