Snap It® Jr Tube Plugs


The Fastest, Most Cost-Effective, and Safest Way to Plug Tubes up to 1,000 PSID

Product Features

• Blowout pressures exceeding 18,000 PSID
• No welding & quick installation saves up to 80% in labor costs
• Through-the-tube plugging - no need to remove rear head cover

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 Jr is rated @ 1,000 PSID!

Save Time & Labor Costs
The Snap It Jr installs in just minutes. You no longer need to remove the rear head cover because "through-the-tube plugging" can be performed. You can also skip the welding required for tube plugs in high-pressure applications, as Snap It tube plugs install in just minutes with a hydraulic ram and create a seal strong enough to hold up to 1,000 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 Jr has been independently verified to keep from blowing out at pressures exceeding 18,000 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 overdriving 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!

Snap It Jr plugs fit multiple tube sizes and are available in numerous materials. 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. Blowout pressure testing was with standard-size tube plugs and in carbon steel and stainless steel.
