SST Vacuum Bagging Connector for Composites
The SST vacuum bagging connector provides a quick, reliable vacuum port on fiberglass or composite bagging jobs. Twist-lock action creates an airtight seal, reducing setup time between layups. It is precision machined from 6061 billet aluminum with a hard anodized finish for chemical resistance, suitable for polyester or epoxy resins. It uses standard ¼” NPT male threads, enabling easy compatibility with existing vacuum hoses and pumps. This accessory helps streamline bagging workflows, especially when frequent port changes or multi-part molds are involved.
Fibre Glast Vacuum Bagging Starter Kit
The Fibre Glast Starter Kit bundles essential components for vacuum bagging carbon, fiberglass, and composites. Included items cover pressure gauges, regulators, fittings, clamps, tubes, and couplings, with compatibility for reusable setups. The kit emphasizes degassing performance by removing air, humidity, and excess resin during layups, contributing to stronger, lighter parts. Manufacturer guidance and videos help users optimize curing, bag integrity, and part stabilization, making it a practical choice for DIY builds and small shops.
VIVOHOME 110V 1/4 HP Vacuum Pump
This single-stage rotary vane pump from VIVOHOME features a die-cast aluminum housing with a compact footprint and a composite anti-slip base. It is suitable for basic degassing, moisture removal in resin systems, and general maintenance tasks around composite projects. The unit includes an oil sight glass and a bottom oil drain valve for easier maintenance, plus a standard ¼” NPT inlet. A bundled oil quantity helps users quickly begin bagging and degassing operations in smaller setups.
VIVOHOME 110V 1/3 HP Vacuum Pump
For larger bagging projects, the VIVOHOME 1/3 HP model delivers increased airflow while maintaining a compact design. It provides efficient moisture removal prior to resin addition, helping improve part stability and resin distribution. Features mirror those of the ¼ HP model—oil sight glass, bottom drain, ergonomic handle, and portable case—giving users a helpful option when bagging bigger composites or multiple parts in a single session.
VEVOR 3CFM Vacuum Pump with Gauges
The VEVOR 3CFM pump targets compact, versatile bagging and HVAC tasks with a compact 1/4HP motor and a high-quality vacuum rating around 5 Pa. The included gauge set provides reliable readings during degassing and resin distribution. Hoses are included and designed for leak-proof connections, with durable rubber construction and multiple connection sizes. This option balances portability with performance for small- to mid-size composite projects.
Buying Guide
- Vacuum level and airflow: For composite bagging, aim for a pump that achieves low vacuum (low Pa) and adequate CFM to suit bag size and resin viscosity. Larger bags and heavier resins benefit from higher CFM and efficiency.
- Port compatibility: Ensure ¼” NPT fittings or adapters match your existing vacuum hoses, bagging film, and port adapters. Quick-connect ports can save setup time on frequent bag changes.
- Maintenance features: Oil sight glasses and bottom drain valves simplify monitoring and maintenance, reducing downtime during long sessions.
- Durability: Aluminum housings and hard anodized finishes help resist chemical exposure from resins and solvents commonly used in composites.
- Kit vs. standalone: Starter kits provide a complete setup with gauges and fittings, which is useful for beginners. Standalone pumps can be paired with your preferred accessories for customization.
- Portability: If your workflow moves between benches or jobsites, consider models with ergonomic handles and compact footprints.
- Support and guidance: Kits offering instructional materials or guided videos can improve results for new users and help optimize degassing and fiber distribution.
