Snap It® Sr - High Pressure Tube Plugs


The Fastest, Most Cost Effective, and Safest Way to Plug Tubes up to 7,000 PSID

Product Features

• No tube sheet damage, no leaks, no worries!
• Blowout pressures exceeding 28,000 PSID
• No welding & quick installation saves up to 80% in labor costs

Product Description

USA Industries' Snap It tube plugs are the major advancement you've been waiting for. Now you can install tube plugs without welding and in 80% less time, avoid tube sheet damage completely, and Snap It Sr is rated to hold pressures up to 7,000 PSID!

Save Time & Labor Costs
The Snap It Sr installs in less than 60 seconds, and you can skip the welding required for tube plugs in high-pressure applications. Snap It tube plugs install in just minutes with a hydraulic ram and create a seal strong enough to hold up to 7,000 PSID. With labor costing more than ever before, you can draw a direct line from saving time on installation to lowering your maintenance labor costs and reducing unit downtime.

Increased Safety
Blowouts from your fin-fan® / air-cooled heat exchanger are extremely dangerous, and in the worst case scenario, can result in death. Snap It Sr has been independently verified to keep from blowing out at pressures exceeding 28,000 PSID. Also, by not requiring welding to ensure a solid seal, you completely remove the risk of a spark igniting dangerous chemicals or fumes.

Extremely Cost-Effective
While Snap It tube plugs have a larger up-front cost, our customers save in reduced labor and shortened unit downtime, resulting in significant savings after just the first use. Most tube sheets need to be replaced after repeated plugging with traditional methods involving welding or over-driving tapered pins. Snap It's unique installation process completely prevents damage to the tube sheets and tube sheet ligaments, which prevents costly maintenance downtime. We have also found that when used to plug tubular reactors, it significantly decreases reloading times due to the plug's design and ability to not hinder the catalyst loading systems!

Tooling for installation and removal is fully compatible with any system, and we can rent or sell equipment to you inexpensively. USA Industries is proud to guarantee a leak-free helium seal to 1 x 10-9 c/sec, providing peace of mind that this plug won't fail!

Note: Always puncture the tube before installing any plug to ensure that pressure cannot build up in the tube and cause the plugs to loosen or blow out. Never stand in front of any installed plug under pressure. Plugs ejected under pressure can cause serious bodily injury.

Snap It Sr - Pressure Rating by Size
Tube ID Range Pressure Rating
0.400 - 0.600 = 7,000 PSID
0.620 - 0.740 = 4,000 PSID
0.760 - 1.000 = 2,000 PSID
