Review: Perfect for camper conversion plumbing - Following lots of YouTube tutorials we were recommended the John guest push and fit fittings. They are easy to use, we have had no leakage issues, just make sure your pipes have a nice clean cut. We also found the little round inserts to keep the piping in a circular shape handy. Great value for money and ease for newbies. Review: Simple plastic adapter that does the job. Very pleased. - Perfect for the job. Easy fit no leak. As a precaution against leaks I bound the threads with thread sealing tape. Used on my caravan so my experience is not related to U.K. mains water pressure. ## Features - Genuine John Guest Fittings: These adaptors are authentic John Guest products, known for their quality and reliability in plumbing systems. - Secure Connection: Designed for easy installation, these adaptors allow you to securely connect 12mm semi-rigid or push-fit pipes to a female 1/2" BSP screw fitting. - Pack of Two: Each pack contains two adaptors, providing you with a cost-effective and convenient solution for your plumbing needs. - High-Quality Construction: Crafted from durable materials, these adaptors are built to last, ensuring a long-lasting and reliable plumbing connection. - Trust in Cool Products: With over a decade of industry excellence, Cool Products is your trusted source for premium plumbing components, dedicated to delivering value and customer satisfaction. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09Q96ZFWW | | Best Sellers Rank | 1,329 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 16 in Pipe Fittings | | Brand | John Guest | | Colour | Black | | Connector Type | Adapter | | Connector type | Adapter | | Country of Origin | United Kingdom | | Customer Reviews | 4.6 out of 5 stars 162 Reviews | | Item Dimensions | 35 x 30 x 30 millimetres | | Item Weight | 0.03 Kilograms | | Item dimensions L x W x H | 35 x 30 x 30 millimetres | | Manufacturer | John Guest | | Material | Plastic | | Model Number | PM011214Ex2 | | Number of Pieces | 2 | | Part Number | PM011214Ex2 | | Size | Klein | | Thread Size | 0.5 inches | | Thread Type | BSP | | Unit Count | 1.0 count | ## Product Details - **Brand:** John Guest - **Colour:** Black - **Connector type:** Adapter - **Item dimensions L x W x H:** 35 x 30 x 30 millimetres - **Manufacturer:** John Guest - **Material:** Plastic - **Number of pieces:** 2 - **Size:** Klein - **Thread size:** 0.5 inches - **Thread type:** BSP ## Images ![Male 1/2" BSP to 12mm Push Fit Water Adaptor **(2 Pack)** - Image 1](https://m.media-amazon.com/images/I/510vZQ4upKL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect for camper conversion plumbing *by A***Y on 16 December 2025* Following lots of YouTube tutorials we were recommended the John guest push and fit fittings.
