About This RV Bulb Seal

Trim-Lok’s All-in-One Bulb Seal is a one-piece seal designed to be installed on the interior RV slide-out wall to compress against the RV slide out when it is not extended to prevent air, moisture, debris and pests from entering at the joint. 

Made of durable TPO and TPV plastic, our RV slide-out bulb seals easily conform to uneven surfaces and regain their shape when the room is slid back in. It can make a 90-degree turn using Trim-Lok’s custom-created notching tool. 

Easy Installation Method

This RV bulb seal comes with tape adhesive for secure and easy installation. Slip coating on the bulb creates a smooth surface to eliminate resistance while using a staple gun. The bulb lifts up and away to reveal a pre-notched drill channel for ease of installation.

Benefits of RV Slide-Out Bulb Seals

Our RV slide-out bulb seal creates a watertight seal between the slide-out room and the RV.  Trim-Lok’s All-in-One Seal system offers improved protection and durability for RVs and campers, with benefits such as:
