Plus Apriximately 1" of threads. ## Frequently Bought Together - 1-1/2 inch Tuuber Vent 2x Superior Seal Air Admittance Valve - Oatey Sure-Vent 1-1/2 in.–2 in. 160 Branch, 24 Stack DFU Air Admittance Valve with White PVC Sch. 40 Adapter - 2-inch Vent Tuuber 2X Superior Seal Air Admittance Valve --- ## 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.jp/products/121878475-1-1-2-1-90od-mnpt-air-admittance-valve](https://www.desertcart.jp/products/121878475-1-1-2-1-90od-mnpt-air-admittance-valve) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-21*
