I also drilled and screwed two sheet metal screws per blast gate (along with silicon sealer) **Q: Are they both 4" od, or is one size 4"id for dc machine port?** A: No, They are 3 11/16 id and 3 13/16 + 1/32 od. There is nothing 4" here. **Q: any suggestions on how to attach this to 4" DWV? The pipe is too large for these.** A: I didn't hook them up to 4inch. I ran 2 3/4 flex and pvc. Btw...it clogs up with saw dust. I drilled a hole on side opposite the slide with a forsner bit to blow it out. I cover the hole with duct tape. **Q: The action on the 4" plastic version is very rough / jerky. Any successful method of smooting the action? Grease?** A: I found it varies from one gate to another. Applying wax from a candle or similar source, helped but did not fully fix the issue. I just rubbed it on the flat portion that fits in the groove and worked it back and forth. I would be afraid that grease would trap dust. I prefer metal gates. ## Frequently Bought Together - POWERTEC 70108 4 Inch Blast Gate for Dust Collector, Dust Collection Fittings - POWERTEC 4 Inch Y Fitting for 4" Dust Collection Hose, 4 Inch Dust Collection Hose Connector Fittings for Dust Collection System, 1 pack (70106) - POWERTEC 70260 4 Inch Key Hose Clamp, Thumb Screw Key Adjustable Stainless Steel Hose Clamps for Dust Collection, Dust Collector and Dryer Vent Hose, Pipe Clamp, RV Clamp, Worm Gear Clamp, 10 pack --- ## 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.gr/products/4132545-70108-4-inch-blast-gate-for-dust-collector-dust-collection](https://www.desertcart.gr/products/4132545-70108-4-inch-blast-gate-for-dust-collector-dust-collection) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-06-25*
