Phillips' STA-DRY QCMS2 Quick Connect Modular System comes as part of an expanding line of STA-DRY sockets, plugs, noseboxes, terminals and electrical harnesses offer fleets the best solution to protecting their electrical systems from corrosion damage. This modular socket/plug hybrid can be semi-hardwired to the tractor creating a complete seal at the seven-way connection. By removing the socket from the union, the QCMS2 mates directly with Phillips' STA-DRY QCS or QCS2 (Quick Connect Socket) boot - standard on most tractor OEM's - so there won't be a break or gap where moisture can enter.
