When installing solar panels, it is not only the main fasteners that are important, but also the components that ensure a tight fit, surface protection and stable performance of the connection. These components include EPDM gaskets and T-bolts.
EPDM gaskets are used as sealing and protective elements in mounting assemblies. T-bolts, in turn, are designed to secure structural elements within mounting profiles. Together, these products help to create a correctly assembled unit for installing solar panels.
How does a T-bolt differ from a standard bolt?
The main feature of a T-bolt is the shape of its head. This allows the fastener to be inserted directly into the mounting profile and, once turned, secured in its groove.
Unlike a standard bolt, a T-bolt does not require a through-hole in the profile for installation. This simplifies assembly and allows the fixing point to be positioned at the required location along the profile.
T-bolts are used in solar panel mounting systems, profile structures and other assemblies where groove mounting is employed. When selecting a T-bolt, it is essential to consider the profile size, the diameter and length of the threaded section, as well as compatibility with the nut and other components of the assembly.
Why is an EPDM gasket needed in a fastening system?
An EPDM gasket fulfils several functions within the assembly. It creates a seal between components, helps to protect the surface from direct contact with metal parts, and compensates for minor irregularities between the surfaces being joined.
EPDM is characterised by its resistance to atmospheric conditions, moisture, temperature fluctuations and ultraviolet radiation. This is precisely why such seals are used in structures operated outdoors.
EPDM gaskets can be used in various assembly configurations depending on the system design and sealing requirements. When purchasing in bulk, it is important to select products not only by size but also according to operating conditions and compatibility with specific fasteners.
How to fit a T-bolt and gasket when installing a panel
Before installation, check that the T-bolt matches the profile and prepare the necessary components. Insert the bolt into the profile groove, then rotate it into the working position so that the head locks into place inside the channel.
Position the EPDM gasket in accordance with the design of the specific assembly. It must lie flat against the surface without any warping or creases. Once all the connection elements have been fitted, they are tightened to the torque specified for the relevant system.
During installation, it is important not to overtighten the fasteners: excessive torque may deform the gasket or damage the surface of the panel or profile. The exact installation procedure depends on the type of mounting system and the assembly design.
Prices and terms for bulk orders
The cost of EPDM gaskets and T-bolts depends on the size, material, specification and the number of items in the order. For manufacturing enterprises, installation companies and distributors, bulk supply allows the necessary components to be purchased in batches in line with current requirements.
If you need to purchase EPDM gaskets for regular installation work, it is advisable to compile a list of the required sizes and quantities straight away. At DINMARK, you can select components for solar mounting systems and order them in bulk.
Benefits of purchasing via the Dinmark B2B portal
The DINMARK B2B portal is designed for the regular handling of wholesale orders. Registered customers can view the available product range, current prices and stock levels directly on the website.
For companies that regularly purchase EPDM seals, T-bolts and other mounting components in bulk, this makes it possible to place repeat orders more quickly and keep track of the items they need.
The account dashboard also offers features for managing products and orders, including ‘Favourites’ lists, reordering and the import of user-defined product codes. For distributors, integration of product range, price and stock data is provided via API and other data exchange formats.
Questions and Answers
Can solar panels be installed without an EPDM gasket?
This depends on the design of the specific mounting assembly. If the gasket is specified by the system manufacturer as a sealing or protective element, it should not be omitted from the design. EPDM helps to ensure the necessary seal and protection of the contact surfaces.
Why EPDM specifically, rather than a standard rubber gasket?
EPDM is designed for use in outdoor environments, where it is exposed to moisture, solar radiation and temperature fluctuations. Therefore, EPDM seals are best suited for use in outdoor mounting structures, particularly in solar panel systems.
How is the price calculated for T-bolts and gaskets when purchased wholesale?
The price depends on the specific size, type and quantity of goods in the order. For regular purchases, you can create an order comprising the required items and check the current wholesale terms in the DINMARK B2B portal.
Where is the AN 172 angle bracket end cap used?
The AN 172 angle bracket end cap is a separate component of the solar mounting system. It is used to cover the end of the corresponding profile element and to complete the mounting assembly. Before ordering, you must check that the end cap is compatible with the specific type of angle bracket.
