Vacuum Breaker Repair Kit. Includes: Cap, Body, and Piston. For use On 4", 6", 8", 10", 12" And 14" T550 And T550A Frost Free Sillcocks. ## Features - Repair kit includes replacement vacuum breaker parts for Legend brand, T-550 and Improved Flow T-550A, anti-siphon frost free sill (i.e. spigot, faucet, hose bib, hose valve). Used on 4", 6", 8", 10", 12" And 14" T550 And T550A. The function of this kit is to prevent water from siphoning back into the potable water Supply (i.e. backflow). - Included with this kit are: 1 stainless steel cap, 1 body (larger plastic piece with rubber o-ring), and 1 piston (smaller plastic piece). Body measurements: The top (Wider) diameter is 1.25" (1 1/4"). The bottom (Narrower) diameter is .875" (7/8"). The threads are proprietary to Legend brand, and non-standard, therefore they will not fit other sill brands. - How do I identify my sill brand, size and model number Markings for Legend, the size and the model number will be visible on the top of the wheel handle. - How do I know if my outdoor faucet is frost free A rule of thumb is that if the faucet has a knob that’s perpendicular to the house, it’s frost–free. The knob turns a long stem that closes a valve inside the house where it’s warm. If the knob is at a 45-degree angle, it’s not frost free. Tip: If your current vacuum breaker has a black cover, this replacement part will not fit. - For correct assembly: The flat end of the piston goes up inside the smaller diameter end of the body. The prongs/teeth of the piston, should be facing out/downward. As you install the body back into the sillcock valve, the prongs/teeth of the piston should be facing downward towards the valve. Check the alignment before tightening. The stainless steel cap secures the assembly in place. Be sure to tighten with a wrench to prevent leaking. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B018HC4PEE | | ASIN | B018HC4PEE | | Additional Features | Safety Feature: Prevents Backflow | | Brand Name | Legend Valve | | Date First Available | 1 March 2016 | | Finish Types | Polished | | Global Trade Identification Number | 00857447008263 | | Included Components | Handle | | Is Discontinued By Manufacturer | No | | Is Electric | No | | Item Weight | 0.05 Kilograms | | Item model number | LEG-108-903 | | Manufacturer | Kelllelldaaa | | Manufacturer | Kelllelldaaa | | Manufacturer Part Number | LEG-108-903 | | Material Type | Plastic, Rubber, Stainless Steel | | Model Name | LEG-108-903 | | Model Number | LEG-108-903 | | Mounting Type | Wall Mount | | Number Of Handles | 1 | | Number of Pieces | 3 | | Product Dimensions | 20.32 x 2.54 x 10.16 cm; 45 g | | Recommended Uses For Product | outdoor | | Room Type | Outdoor | | Spout Design | curved | | UPC | 857447008263 785577041976 782247999919 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Legend Valve - **Finish type:** Polished - **Material:** Plastic, Rubber, Stainless Steel - **Mounting type:** Wall Mount - **Recommended uses for product:** outdoor ## Images ![Legend Valve 108-903 T-550 VACUUM BREAKER REPAIR KIT by Legend Valve - Image 1](https://m.media-amazon.com/images/I/41CKGqtH-CL.jpg) ## Frequently Bought Together - KNOWAIR LEG-108-903 Vacuum Breaker Repair Kit - Homewerks VACVBKX1B Vacuum Breaker Replacement Kit for Traditional Anti-Siphon Frost-Free Sillcock Valves - Eastman Vacuum Breaker Repair Kit, 45417 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/282375915-legend-valve-108-903-t-550-vacuum-breaker-repair-kit](https://www.desertcart.vn/products/282375915-legend-valve-108-903-t-550-vacuum-breaker-repair-kit) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-14*
