Twist-Lock vs. Push-In — Why It Matters
Standard push-in pump heads seat onto the cylinder by pressing straight in — a simple connection that works adequately for most users but can allow micro-movement at the junction during pump strokes, reducing vacuum consistency. The twist-lock connection requires rotating the pump head to lock it onto the cylinder, creating a mechanically secured joint that resists movement during pumping. The result is a tighter, more consistent vacuum seal with each stroke — the same connection advantage used on the BOS-3 Automatic 3000 battery system extended to manual operation.
Two Reasons to Order This Head
Replacement
If your MVP 700 pump head has worn out or failed while your cylinder remains in good condition, replacing the pump head alone restores full system function at a fraction of the cost of replacing the complete system. The twist pump head fits directly onto your existing twist-compatible cylinder.
Upgrade
If you currently have a push-in manual pump head and want the improved vacuum consistency of a twist-lock connection without purchasing a complete new system, this pump head provides the upgrade while keeping your existing cylinder and accessories.

FAQs
Is this the same as the standard MVP 700 replacement pump head (M107)?
The M107 is the OEM push-in replacement head for the standard MVP 700. This twist pump head uses a twist-lock connection for a more secure cylinder seal — a different connection type providing improved vacuum consistency. If you want the original push-in connection, the M107 is the direct OEM replacement. If you want the twist-lock upgrade, this is the head to order. Call us to confirm which is right for your cylinder: 866-218-0902.
Do I need a different cylinder for this head?
If your existing cylinder is a twist-compatible Pos-T-Vac cylinder, no — this pump head will fit directly. If your current cylinder is a push-in slip type, you will need to replace the cylinder as well as the pump head, since twist and slip connections are not interchangeable. See the Pos-T-Vac Twist Cylinder if you also need a replacement cylinder.
Can I switch between this manual head and a battery head on the same cylinder?
Yes — if your cylinder is twist-lock compatible, both the manual twist head and the BOS-2000-3 battery head will fit the same cylinder. You can own both heads and switch between manual and automatic operation using one cylinder — effectively creating a dual-mode setup. Call us if you'd like to discuss: 866-218-0902.
