SPGTM-5 Vacuum Breaker Adapter 4-Pack - Fixes Leaks Fast

In this review of the SPGTM-5 Vacuum Breaker Adapter 4-Pack the bottom line is simple: it is for homeowners and gardeners who need a reliable way to convert spigots with external vacuum breakers into a normal garden hose connection that does not leak. The reviewer found the adapters save time compared with trying to repair corroded set screws or replacing the entire vacuum breaker, and they install in minutes. This is a practical fix for frost-proof hose bibs, irrigation timers, or any always-on connection where a leaking vacuum breaker is a persistent problem.

Key Features

• Made in the USA: Precision machined locally for consistent fit and durability under outdoor conditions.
• Fits newest Arrowhead models: Specifically designed to work with Arrowhead 255BFP and 355BFP spigots and the PK1390 stamped ABP 59 BFP bottom half, so users with those fittings get a direct solution.
• Thread compatibility: Fits spigots with a 1.17 in-1.18 in outer thread diameter and 1.14 in-1.15 in internal thread diameter to ensure a snug, leak-free connection.
• Quick installation: Removes the need to extract corroded set screws or disassemble the top half of a vacuum breaker, letting users attach a normal hose in minutes with two wrenches.
• Multiple models available: Part of a seven-model family so customers can match their spigot thread size by measuring and choosing the correct adapter.

Who It's For

This adapter is ideal for homeowners, gardeners, and small property managers who face leaking external vacuum breakers, especially where hard water or irrigation timers keep the water on for extended periods. Installers who prefer a straightforward replace-and-go approach will appreciate being able to leave the top of the vacuum breaker in place.

It is not for users who have nonstandard thread sizes outside the specified 1.17 in to 1.18 in outer thread range or who need a complete replacement vacuum breaker with integrated sealing features. Those customers should measure their spigot threads and consider other models or a full vacuum breaker replacement.
