Not a direct fit. Joining Duotight 8mm push-in to Duotight 9.5mm push-in needs a Duotight 8mm to 9.5mm reducer.
The two ends
- End A
- Duotight 8mm push-in (8 mm (5/16") OD)
- End B
- Duotight 9.5mm push-in (9.5 mm (3/8") OD)
- A seals on
- double EPDM O-ring on the tube outer wall
- B seals on
- double EPDM O-ring on the tube outer wall
- Part needed
- Duotight 8mm to 9.5mm reducer
The part to buy
An 8mm Duotight body will not accept 9.5mm tube and a 9.5mm body will not grip 8mm tube. To step between EVABarrier 8mm and 9.5mm line you fit an 8mm to 9.5mm Duotight reducer, which is a push-in on each size.
Do not try to force 9.5mm tube into an 8mm collet by trimming it. The double O-ring is sized for the tube wall and a shaved tube will not seal. Use the reducer.
