Push-in cross fittings provide a quick and secure method of creating four-way tube connections within pneumatic systems. The push-fit design allows fast installation without tools, giving a reliable, leak-free joint that can be disconnected when required for maintenance or system changes. These fittings are designed for compressed air only (not water or other gases), with a working pressure of 0–150 psi (10.3 bar) and a temperature range of 0 °C to 60 °C. Ideal for workshops, industrial plants, and OEM applications needing compact four-way branching. We can supply the full range and usually deliver quickly – please contact us if you need sizes not listed.
