The male threads of the couplings and nipples are Teflon coated. The eSafe version of the 310 series disconnects in two stages to purge the coupling and minimize the risk of whiplash, which can cause injury to the operator. One-handed operation ensures easy handling. The eSafe version complies with ISO 4414 and EN 983 standards.
The 310 series is available in eSare, Soft-Line and Multi-Link versions.
