Tight quarters? No problem. Nelson's line of Space Saver Silencers are the answer when space is limited and a medium to high degree of silencing is required. Like our complete line of silencers, our space saver models can be conveniently mounted in any position and feature all welded construction, an "F" mounting flange (standard in sizes 4" to 14") and "S" slotted pipe ends available in sizes 2" through 6". Companion flanges are also available for 4" to 22".
