Easy to install liner clips for almost every tank rim configuration

Prior to our invention of WittclipTM fasteners, most drop in liners were secured in tanks using drawstring rope. The problem with rope is that it doesn't securely lock the tank liner to the rim of the tank. When the tank is filled with solution the liner can be pulled into the tank a bit, greatly affecting how the liner fits. The larger a liner is, the more pronounced this problem becomes.

To solve this issue, Witt Lining Systems invented the WittclipTM fastener. Wittclips are u-shaped stainless steel clips with a threaded bolt welded on one end. Wittclips securely hold the liner to the lip of the tank so that when the tank is filled, rather than pulling the liner into the tank, the weight of the solution pushes the tank liner flush to the sidewalls making for a perfect fitting liner.

We have twelve styles of Wittclips to handle most any tank rim configuration. We have different leg lengths to handle different rim sizes and clips with varied distances between the legs to handle rim thicknesses up to 2 in. thick. We also have a clothespin style Wittclip that can be used on tanks that have no rim at all.

Other Accessories

Bulkhead Fittings

Bulkhead fittings are plumbing connections that make a sealed fitting for outlets in conjunction with a flexible PVC tank liner. They come in a variety of sizes, material constructions, and plumbing connections.

Welded-in Outlets

Liners can be built with outlets to fit through piping with a flange faced connection.  They can be built into the liner or made separate and welded on after the liner is installed.

Witt Overflow Setup

A bulkhead fitting with a slotted PVC pipe is the easiest way to provide an overflow weir with a flexible PVC tank liner.

Compression Strips
Pre-Drilled & Un-Drilled

Rigid compression strips are ideal for installing Witt liners in a concrete application or when there is limited access to the tank rim.  Made from polypro or HDPE they come standard and pre-drilled.

Witt Posi-Flange
Heavy duty fitting

The Posi-Flange advantage is its strength. A compression seal is accomplished by stainless steel nuts and bolts. This is very desirable when a valve or pump is mounted on immediate piping. The Posi-Flange provides a female thread fitting. No metal is exposed to solution.

Koroseal® RibLok
Embed Strip

An embed strip designed to provide the best surface for termination and attachment of a Witt PVC lining in new concrete.

Since 1972 we have been the industry leader in providing flexible PVC corrosion resistant liners. Flexible liners are a cost effective alternative to bonded Linings and coatings. Flexible PVC liners are used in plating tanks, chemical tanks, storage tanks, waste water treatment pits, secondary containment, cooling towers, pits, sumps, solar heated water storage tanks, or anywhere liquid containment or corrosion protection is desired.

Industries served include metal finishing, plating, anodizing, aerospace, oil and gas, mining, municipal water treatment, and food and agriculture. Witt offers a variety of materials such as Koroseal®, Spectra Blue® and Exceline®.  Witt Lining Systems also offers alternatives to PVC, custom fabricating Teflon® , Kynar® PVDF , and XR-5® liners. Wiitt offers a variety of liner grades and thicknesses to suit your lining need.  Links
