Rim-Mounted Secondary Seal
The SealMaster floating roof seal system was developed over 35 years ago, with the goal of making a seal that adjusts to the irregularities of rim spaces while remaining gas tight and virtually maintenance free. The solution is the SealMaster seal system.

Benefits
- Best available technology for emissions and product loss reduction
The SealMaster is designed with guidance from EEMUA 159, with a standard working range of R(-X/+3X), highest BREF scoring and best KRA loss factor per EPA chapter 42. - Excellent working range
The SealMaster can be designed to either EEMUA R(-X/+3X) or API (+/- 4”) working range standards. - Good weather protection
To prevent ingress of rainwater - Worry-free operation
The SealMaster centers the floating roof, dampening horizontal roof movement so the floating roof will not be blocked and the rim seal does not get squeezed in between the floating roof and the tank shell.
Design features
Abrasion and UV resistant materials
Sliding parts in contact with the tank shell are abrasion resistant for longevity.
Flexible assembly
Conforms well to tank-shell anomalies to ensure no gaps.
Multiple-wiper tip navigates all traditional shell constructions
Suitable for service in butt-welded, lap-welded, or riveted storage tanks.
