Duotight - 8mm (5/16") Screwlock x 8mm (5/16") Elbow

Duotight - (5/16") Screwlock Elbow

The duotight 8mm (5/16") Screwlock × 8mm (5/16") Elbow gives you a secure, right‑angle connection where extra strength and stability are required. One side features a standard duotight push‑fit port, while the other uses a compression‑style Screwlock design — ideal for rigid ports, fixed fittings, or situations where you want a reinforced hold.

Like all duotight fittings, this elbow uses the signature double O‑ring sealing system, delivering twice the sealing surface of standard push‑fit connectors. This means tighter hose bends, fewer leak points, and long‑term reliability across gas and clean‑liquid applications.

No clamps are needed — simply cut your EVABarrier line straight, push it in, and enjoy a secure, gas‑tight seal rated up to 100 psi. To remove, press the collet in and pull the line out.

Why duotight? Double O‑Rings = Double Reliability

• Two EPDM O‑rings per port
• Superior sealing surface vs. single‑ring fittings
• Better resistance to gas, chemicals, and pressure cycling
• Allows tighter bend radius without leaks
• Long‑lasting, food‑grade performance

This combination makes duotight the most reliable push‑fit system on the market.
