Push-in unequal Y pieces provide a simple and effective way to branch one tube into two lines of different sizes within pneumatic systems. Their push-fit design allows quick, tool-free installation while ensuring a secure and leak-free seal that can also be disconnected when required. Designed for compressed air only (not water or other gases), these fittings are rated for 0–150 psi (10.3 bar) and operate within a temperature range of 0 °C to 60 °C. Ideal for workshops, industrial facilities, and OEM applications where mixed tube sizes need to be connected neatly. We can supply the full range and usually deliver quickly – please contact us if you need sizes not listed.
