[Viking](https://www.vikinggroupinc.com/) announces its new line of **InstaSeal**®** Sprinkler Head Adapters manufactured with BlazeMaster**® **CPVC,** designed to speed installation with **no need for thread tape or sealant**. The adapters’ **full** **brass thread inserts prevent the potential for cross-threading** while providing a **tight seal **every time via its **EPDM seat**.

For use with sprinklers having a K-factor of 5.8 or less, the InstaSeal adapter makes final sprinkler positioning adjustable, simplifying pendent or horizontal sidewall sprinkler alignment.

 

## **Installation Made Easy**

The InstaSeal adapter saves time on the job by eliminating the need to thread-wrap or add sealant to sprinkler heads. Installation instructions are simple:

1. Hand tighten until the sprinkler head makes contact with the adapter’s rubber seat.
2. Tighten with an additional ½ to 1¼ turn by hand or with the recommended wrench to complete the installation.

Gasket replacement is simple, using a tool specially designed for InstaSeal adapters. When replacing a sprinkler head on a system that's been in use for over 6 months, Viking recommends replacing the gasket of the SHA for that specific sprinkler head to ensure system integrity.

 

## **In-stock Today… And There’s More to Come!**

InstaSeal adapters are in stock and available at [Viking SupplyNet](http://supplynet.com/) and several select distributors. Current availability includes:

- ¾ ” x ½” slip x thread and spigot x thread
- 1” x ½” slip x thread and spigot x thread

More adapters will be available later this year.

Viking offers three unique sprinkler head adapters, offering flexible options for unique fire protection challenges.
