Compression fittings are a common type of LDPE fittings that use a compression nut and ring to create a tight seal around the pipe or tubing. They are widely used for secure connections in plumbing and irrigation systems. LDPE pipe is very commonly used in micro-irrigation systems because it is easy to work with and is generally robust enough to withstand the rigours of gardening. It offers some flexibility due to its low-density, but corner connectors (elbows) are a good idea to prevent kinks in the pipe when navigating around the garden. It is possible to use barbed fittings to achieve a secure and leak-free seal, and there are options for compression fittings to use with LDPE pipe as well for an extra secure fit.
