The F..-MSF female coupling (sleeve) is a highly practical component designed to provide both physical and thermal continuity when joining two male-ended (nipple-sized) fittings within the FOAM System. This fitting overlaps two such male components—like an elbow, T-piece, or reducer—on both sides. The factory-fitted rubber foam insulation ensures that thermal breaks are eliminated, complementing the entire system of insulated ventilation and air-conditioning ducts and fittings.
The F..-MSF acts as a seamless connector, allowing installers to combine various fittings while preserving the airtight and thermally protected envelope of the ductwork.
Consistency is key across the FOAM System. The F..-MSF is manufactured to a uniform length regardless of the diameter, simplifying inventory and installation planning.
The product is available with the four standard insulation thicknesses:
| Nominal Diameter Ød (mm) | Overall Length L (mm) |
|---|---|
| 80 - 250 (All sizes) | 78 |
