High-performance balanced single regulator set with R4 TEC dry chamber diaphragm 1st stage and TEC1 2nd stage, supplied with a choice of hose, regulator bag, and EN250A certification for cold water.

The Tecline R4 TEC1 regulator set, available on DIR-STORE, is a lightweight, versatile, and highly reliable system designed to meet the demands of cold water diving. Combining the compactness and perfect insulation of the R4 TEC diaphragm first stage with the flexible adjustment of the pneumatically balanced TEC1 second stage, this set rigorously exceeds the requirements of the European standard EN250A.

An excellent configuration for stage and decompression cylinder regulators as well as advanced single or twin cylinder kits, it comes complete with a red Tecline bag and total freedom in choosing the type and length of the hose.
