duotight - 9.5mm (3/8”) Female x 9.5mm (3/8”) Female Bulkhead with Locknut

This duotight push-fit fitting is a 9.5 mm (3/8") female-to-female joiner featuring a heavy-duty bulkhead and locknut, making it effortlessly simple to pass lines right through the wall of a tank, housing, or panel. With pure leak-free magic under the hood, all you have to do is secure the bulkhead in place and push your tubing straight in from both sides for an instant, airtight seal. Engineered with robust dual EPDM O-rings, it handles solid working pressures with total ease—no clamps, no hassle, and no stress. Whether you are running draft beer lines, water setups, or custom gas manifolds, this nifty connector delivers tool-free quick connections that hold tight every single time.

Applications & Compatibility

• Line continuity: Keep your 9.5mm OD line secure through walls up to 22mm - just drill a 20mm hole through and screw this on.
  
• 9.5mm OD: Suitable for use with any 9.5mm OD hose or duotight stem.

The duotight Generation 2 Difference

Why settle for standard push-in fittings? duotight Generation 2 represents a massive leap in engineering over traditional acetal fittings.

Dual-Material Double O-Ring Design

The secret to our superior seal is a two-stage system using two different high-quality materials:

1. EPDM O-Ring: Provides exceptional chemical and gas resistance.
2. Silicone O-Ring: Maintains its shape and elasticity in sub-zero temperatures.

High-Performance Materials (POK)

Instead of standard Acetal, Generation 2 fittings are made from Polyketone (POK).

• Higher Chemical Resistance: Withstands harsh brewery cleaners.
• UV Protection: Won't become brittle over time.
• Extreme Durability: Rated for over 300psi @ 25°C.

User-Friendly Features

• Color-Coded Collets: Blue denotes 9mm (3/8").
• Depth Indicators: Includes >| |< indicators so you know the hose is fully seated.
• No Clamps Necessary: Simply push to seal; push the collet to release.

We recommend using a Tube Cutter to ensure a perfectly straight, burr-free cut. An angled cut is the #1 cause of leaks in push-fit systems.
