Intex 38mm hose to 50mm bypass connection for heating unit.

Here's a Simple Adapter You Can Attach Directly to Your Bypass Kit Using 50mm Pipe Holes and Intex Fittings with 38mm Screw-On Connections. This Adapter Ensures Optimal Pump Water Flow, Unlike the Included Fittings That Don't Properly Fit Intex 38mm Hoses. This Adapter is Designed Specifically for Use with Ultra Frame Pools, Which Often Come Equipped with These Types of Fittings. By Attaching It to Your Bypass Kit, You Can Achieve Maximum Pump Performance and Efficiency. I Currently Have This Adapter Printed and Tested, and I Can Confirm That It Fits Perfectly. However, Due to Concerns Over Deformation Under Direct Sunlight, I Chose Not to Use It Myself at the Time of Writing. If Anyone Would Like to Print a Replacement Adapter Using a More Heat-Resistant Material Than PLA, Please Feel Free to Contact Me. Although I'm Not Convinced That This is Necessary, as the Adapter Will Typically Be Out of Direct Sunlight and Water Will Keep It Cool Throughout Use.
