Apeks TEK3 Complete Twinset Regulator Set
By Apeks | Dedicated Left & Right Twinset First Stages | Dual XTX50 2nd Stages | Cold-Water Certified
Designed specifically for double-tank manifold configurations, the Apeks TEK3 Complete Twinset Regulator Set solves the hose routing challenges inherent to technical twinset diving. Featuring dedicated, mirrored left-hand and right-hand first stages, the TEK3 routes all low-pressure and high-pressure hoses straight down alongside the cylinders. This eliminates hose bowing, drastically lowers snag hazards in overhead environments, and provides clear, unobstructed access to cylinder valve handwheels and manifold isolator bars.
Each first stage is machined from a solid, compact brass forging and utilizes an environmentally dry-sealed, over-balanced diaphragm mechanism that excels in freezing Pacific Northwest conditions. Paired with two pneumatically balanced XTX50 second stages, a 2.1m primary long hose, and a backup necklace regulator, this turn-key system delivers exceptional gas flow and total control at any technical depth.
Mirrored Manifold Geometry & Downward Port Angles
Unlike standard first stages that require awkward hose bending across manifold crossbars, the TEK3 first stages feature dedicated LH and RH port orientations. With 3 medium-pressure ports and 1 high-pressure port angled cleanly downward on each post, your long hose, backup regulator, wing inflator, drysuit hose, and SPG route straight along the body with zero kinking.
TEK3 First Stage Highlights
- Dedicated Mirrored LH & RH Bodies: Custom engineered as specific left-post and right-post regulators to maintain perfect symmetry and clean manifold clearance.
- Over-Balanced Diaphragm Mechanism: As depth increases, intermediate gas pressure rises faster than ambient water pressure, ensuring effortless breathing delivery at extreme technical depths.
- Downward Angled Ports: Each post provides 3 medium-pressure ports (3/8" UNF) and 1 high-pressure port (7/16" UNF), all facing downward to eliminate hose stress and snags.
- Environmental Dry Chamber Seal: Completely isolates the main spring chamber from surrounding seawater, preventing internal ice crystallization and keeping silt and contaminants out.
- Heavy-Duty 300 Bar DIN Handwheel: Solid metal DIN connector rated to 300 Bar (4350 psi) with tactile grip ribs for secure tightening with cold-water gloves.
XTX50 Second Stage Highlights
- Pneumatically Balanced Performance: Balances gas pressure across the demand valve seat for smooth, quiet, and consistent air delivery regardless of remaining tank pressure.
- 2-Stage Progressive Purge: Press the edge of the purge button for low-flow delivery (ideal for gentle lift-bag fills), or press dead centre for maximum flow when clearing the regulator.
