Removing this important part and selling it at this high cost is a marketing trap for unwary consumers. Review: buon raccordo per pompe sommerse - Il prodotto è di buona fattura e utilizzabile per portare alla dimensione di 3/4 il tubo di uscita della pompa. Il rischio di avere un raccordo di questo tipo vicino all'uscita della pompa è quello di sovraccaricarla troppo e di romperla. Al momento questo non è accaduto, ma è un rischio da valutare. indubbiamente poter utilizzare un tubo da 3/4 rispetto a quello da 1 pollice permette maggiore versatilità nell'impianto. Perfettamente funzionante la valvola di non-ritorno in plastica. ## Features - Pump adapter with check valve. - Vacuum resistant connection - Attaches suction hoses to pumps - This is for garden pumps - Suitable for domestic pumps ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000OS2K56 | | Brand | KÄRCHER | | Brand Name | KÄRCHER | | Color | Black | | Colour | Black | | Connector Type | Adapter | | Connector type | Adapter | | Country of Publication | Italy | | Customer Reviews | 4.4 out of 5 stars 1,897 Reviews | | Global Trade Identification Number | 04039784223264 | | Included Components | 1 x Kärcher Pump Connector Set for 3/4-Inch and 1-Inch Suction Hose, Black | | Item Dimensions | 41 x 65 x 41 millimeters | | Item Length | 130 Centimeters | | Item Type Name | Pump Connector Set | | Item Weight | 0.04 Kilograms | | Item dimensions L x W x H | 41 x 65 x 41 millimeters | | Manufacturer | Kärcher | | Manufacturer Part Number | 6.997-359.0 | | Material | Plastic | | Material Type | Plastic | | Model Number | 6.997-359.0 | | Number of Pieces | 4 | | Size | 1 inches | | Thread Size | 33,3mm | | Thread Type | G1 | | Unit Count | 1 Count | ## Product Details - **Brand:** Karcher - **Colour:** Black - **Item weight:** 0.04 Kilograms - **Material:** Plastic - **Product dimensions:** 130L x 100W centimeters ## Images ![Karcher Pump Adapter with Check Valve – Small Hose Connector for Secure Water Flow & Backflow Prevention - Image 1](https://m.media-amazon.com/images/I/719E82qwHqL.jpg) ## Customer Reviews ### ⭐⭐⭐ Essential accessory at very High Price *by M***R on 29 November 2020* This is an essential obligatory accessory at a very high price I cannot understand WHY Karcher does NOT include it with their submersible pumps like other makes.
