This connector was perfect to attach a corrugated pipe to a PVC pipe. The clips worked perfectly to keep the flex pipe attached. I also used flex tape to seal the connection. Review: Great product - Well made product and worked great for my application, i wish i found this sooner. ## Features - Connects 4" corrugated pipe to 4" SDR35 pipe or 4" SCH40 pipe ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B085S7F7LF | | Best Sellers Rank | #28,038 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #793 in Pipe Fittings | | Brand | Polylok | | Brand Name | Polylok | | Color | White | | Connector Type | Adapter | | Customer Reviews | 4.6 out of 5 stars 210 Reviews | | Item Dimensions | 4.57 x 4.5 x 4.5 inches | | Item Weight | 0.12 Kilograms | | Item dimensions L x W x H | 4.57 x 4.5 x 4.5 inches | | Manufacturer | Polylok | | Material | Polyvinyl Chloride | | Material Type | Polyvinyl Chloride | | Number of Pieces | 1 | | Size | 4 Inch | | Thread Size | 4 inch | | Thread Type | NPT | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Polylok - **Color:** White - **Connector Type:** Adapter - **Item Weight:** 0.12 Kilograms - **Item dimensions L x W x H:** 4.57 x 4.5 x 4.5 inches - **Material:** Polyvinyl Chloride - **Number of Pieces:** 1 - **Size:** 4 Inch - **Thread Size:** 4 inch - **Thread Type:** NPT ## Images ![Polylok 4" Corrugated Pipe Adapter (4" corrugated to 4" SDR 35 or 4" SCH 40) - Image 1](https://m.media-amazon.com/images/I/41Tx1Cr9AkL.jpg) ## Questions & Answers **Q: How many do you get for $45?** A: One **Q: Does this come in 3 inches?** A: No, currently only manufactured in 4" and 6". **Q: How many for $45?** A: One **Q: Absolute ripoff!
