Snap It Plugs should always be installed within the rolled section of the tubesheet. If the tubes are not rolled into the tubesheet, consult USA Industries (1-800-456-8721) before proceeding. Remove scale and pitting with USA Industries’ Snap It Brushes prior to installation. Any weld droop should be removed prior to plug installation.

Snap It® Jr. Mechanical Tube Plug

Snap It Jr. Tube Plugs - The Fastest, Safest, Most Cost-Effective and Reliable Way to Plug Tubes. Rated up to 1,000 PSID

USA Industries' Snap It® Jr. Mechanical Tube Plugs is the major engineering 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 Mechanical Tube Plug installs in just minutes. You do not 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. 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. The Snap It Jr tube plug is verified to keep from blowing out at pressures that exceed 18,000 PSID. Also, because no welding is required to ensure a solid seal, you completely remove the risk of a spark igniting dangerous chemicals or fumes.

Extremely Cost-Effective

Snap It engineered tube plugs have a larger up-front cost, but customers will save in reduced labor and shortened unit downtime. This will result in significant savings after just the first use. Because most tube sheets must 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. 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!

The Snap It Jr Mechanical Tube Plugs fit multiple tube sizes and are available in numerous materials. Tooling for installation and removal is fully compatible with any system, and we will 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 and will provide peace of mind that this plug will not 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.
