Western Square Back Non-Drain Gasket, 4" (G48)

The G48 is a 4" Western square back non-drain replacement gasket for surface irrigation pipe couplings. The square back profile provides a firm, compression-fit seal in Western-style couplings, and the non-drain design keeps water in the pipe between sets — ideal for systems where you want to maintain line pressure or minimize refill time. A worn gasket is one of the most common causes of coupling leaks, and keeping spares on hand means you can fix a leak in minutes rather than losing a set.
