Sprinkler Identification Numbers

This searchable list connects contractors and facility managers with a match for existing sprinklers and accessories

Every fire sprinkler manufactured in the past 19 years has a sprinkler identification number (SIN). And when it comes to replacing an existing head—or locating compatible accessories, like escutcheons, wrenches, or cover plates—the SIN provides an essential starting point.

This guide—and the accompanying directory—was created to:

  • Help consumers quickly understand essential characteristics of their sprinklers
  • Make finding a substitute for discontinued heads simple
  • Connect buyers to identical sprinklers and compatible accessories

To do that, we've grouped similar types of fire sprinkler heads together across four leading manufacturers: Senju Sprinkler, Tyco, Victaulic, and Viking. Each entry includes the SIN, the manufacturer's part number(s), thread size, K-factor (orifice size), and a basic description. If you have a sprinkler identification number handy, you can either:

  • Search for it by pressing Control-F (Windows) or Command-F (Mac). Type in the SIN to find a match. Once you find it, click on the link in the table to run a search of QRFS’s inventory for sprinklers and compatible accessories.
  • Browse by category using our table of contents

You're welcome to skip ahead, but be warned: knowing the SIN may not be enough. While each SIN refers to very specific sprinkler head types, or models, it doesn't specify a temperature or finish. If you'd like an introduction (or a refresher), read on before browsing or searching our directory.

You can check out our online selection of sprinklers, escutcheons, cover plates, wrenches, and more.

Sprinkler identification numbers specify a model but not an exact match, leaving consumers and contractors with some challenges

Sprinkler identification numbers help to distinguish between different types of fire sprinklers—but they're not always enough

Here's why you really need to know about SINs: leading fire codes require an exact or nearly exact match between sprinklers and common accessories. A broken or damaged cover plate needs the manufacturer's recommended replacement. The same goes for many escutcheons (sometimes called "trim plates"). Even the wrenches kept in spare sprinkler cabinets should be "specified by the manufacturer." The SIN helps consumers track down compatible parts or, in the case of broken/obsolete sprinklers, acceptable substitutes.

Let's get to it: a sprinkler identification number consists of one or two letters followed by three or four numbers. That code is imprinted on each sprinkler's deflector—the thin metallic part furthest away from a sprinkler's threaded inlet. Today, they're everywhere, thanks to recommendations from the National Fire Protection Association (NFPA). And guidelines from the International Fire Suppression Alliance (IFSA) require a new SIN for each variation in:

  • Orifice size (K-factor)
  • Response type (with "quick response" and "standard response" as the two leading kinds)
  • Distribution characteristic (including whether a sprinkler stands upright, points down, or mounts sideways)
  • Maximum working pressure

But one SIN may encompass several different temperature ratings, finishes, and approvals. (To get an exact match, you'll want to follow the steps outlined in our guide to sprinkler replacement). Further, these codes aren't uniform. Each one-or-two-letter prefix represents a manufacturer. Some of those prefixes include:

  • C, CS: Central Sprinkler
  • F, G: Grinnell Corporation
  • GL, GS: Globe Fire Sprinkler
  • GV: Victaulic Company
  • R, RA: The Reliable Automatic Sprinkler Co., Inc.
  • S: Star Sprinkler Inc.
  • SS: Senju Sprinkler Co., Ltd.
  • TF, TY: Tyco Fire/Tyco International
  • V: Victaulic Company
  • VK: The Viking Corporation Ltd.

However, the numbers that follow are assigned as that manufacturer sees fit. For example, VK101, V101, and SS101—Viking, Victaulic, and Senju sprinklers, respectively—may have nothing in common, other than the fact that they're all sprinklers.

Picture of Tyco Fire Sprinklers

All three of these sprinklers share the same SIN—TY315—but activate at significantly different temperatures (as their colored bulbs indicate).

Our directory lists major types of fire sprinklers along with key ordering information

At the time of writing, there doesn't appear to be a single, open-access database for the world's sprinkler identification numbers. Some offerings come close: Product iQ™, a database operated by the safety science giant UL, allows (registered) users to search a list of their certified sprinklers.

In an effort to fill that gap, we've created a directory that separates SINs by sprinkler-head type. For the most part, these are organized by the sprinkler's K-factor, which measures how much water passes through the sprinkler. It's one of a few "operating characteristics" that must remain the same whenever a sprinkler is replaced. Sorting by K-factor makes it easier to find that match.

If the exact model isn't available, another brand or model may work as long as it has the same:

  • Temperature rating
  • Style and design requirements (is it a storage sprinkler, for example?)
  • Deflector type (is it a pendent, upright, or horizontal sidewall head?)
  • Special coatings (such as those that resist chemical corrosion)

If you find the sprinkler identification number you're looking for, click on the SIN for a list of sprinklers and related products in stock at QRFS.

Remember, the easiest way to use the below table is to search for your SIN by pressing Control-F (Windows) or Command-F (Mac). Type in the SIN to find a match. Once you find it, click on the link to see a search of QRFS for sprinklers and compatible accessories.
