Tyco Model DSB-2 Dry Sprinkler Boot – P/N 63-000-0-002

Engineered Protection for Freezer Installations

The Tyco Model DSB-2 Dry Sprinkler Boot (P/N 63-000-0-002) is a purpose-built solution designed to enhance the performance and longevity of Tyco dry-type sprinklers used in freezer and cold storage applications. This innovative accessory plays a critical role in preventing ice build-up caused by air leakage around the sprinkler barrel, a common challenge in environments with extreme temperature differentials.

Constructed from a durable EPDM and rubber blend, the Model DSB-2 boot securely seals the annular space between the sprinkler and the clearance hole through freezer ceilings or walls. By effectively stopping the exchange of warm, moist air into cold environments, the boot mitigates the formation of condensation—protecting both the sprinkler and the integrity of the fire protection system.

Key Applications and Advantages

Ideal for use in insulated freezer structures, the DSB-2 boot supports the continued reliability of dry sprinklers in wet pipe systems exposed to freezing temperatures. It enables compliance with NFPA 13 (2022), Section 15.3.3, which mandates sealing around the barrel of dry sprinklers penetrating freezer enclosures.

Unlike temporary or improvised sealing methods, this boot offers a long-term, crack-resistant seal—eliminating concerns over degraded caulking or improper gap filling. The included ethyl cyanoacrylate adhesive delivers instant, reliable bonding to metal, plastic, or rubber surfaces, while nylon strap ties ensure a secure mechanical grip.
