For professionals across manufacturing, automotive, aerospace, and industrial maintenance, achieving a perfect, lasting seal is non-negotiable. At Kaxite Sealing, we engineer sealing solutions that withstand extreme pressures, temperatures, and chemical exposures. Our flagship gasket tape represents the pinnacle of this commitment—a versatile, high-performance sealing material designed for reliability, ease of application, and long-term cost savings. Unlike traditional pre-cut gaskets, our tape form allows for on-site fabrication of custom seals, eliminating downtime waiting for parts and reducing inventory needs. This guide delves into the technical specifications, applications, and expert knowledge surrounding premium gasket tape.
Our gasket tape is developed through rigorous R&D to solve common sealing failures. Here’s what sets it apart:
Selecting the correct gasket tape requires understanding its technical capabilities. Below are the key parameters for our standard product line. Custom formulations are available upon request.

Proper installation is critical to performance. Follow these steps for a flawless seal:
Q: Can your gasket tape replace any pre-cut gasket?
A: In the vast majority of applications, yes. Kaxite Sealing gasket tape is specifically engineered as a universal replacement for conventional sheet gaskets. It is ideal for flat, raised-face, and some grooved flanges. However, for extreme high-pressure (ASME Class 1500+) or specialized spiral-wound/metallic gasket applications, a technical consultation is recommended to confirm suitability.
Q: How do I choose the right material grade (KT-250, KT-450, etc.)?
A: Selection is based on the media being sealed and the operating temperature. Use KT-250 (NBR) for general-purpose oil and fuel applications. For extreme high or low temperatures (ovens, coolant lines), choose KT-450 (Silicone). For aggressive chemicals like strong solvents or acids, KT-350 (FKM) is required. For outdoor/weathering or hot water/steam, KT-150 (EPDM) is optimal. Our website has a detailed selection guide, and our technical team can assist.
Q: Does the tape have an adhesive, and is it strong enough?
A: Yes, our tape features a high-tack, pressure-sensitive acrylic adhesive on one side. It is designed to hold the tape securely in place on vertical or overhead surfaces during assembly, preventing slippage. The primary sealing force, however, comes from the bolt compression which compresses the tape's core material. The adhesive is a positioning aid, not the main sealing mechanism.
Q: What is the shelf life of Kaxite gasket tape, and how should I store it?
A: When stored in its original packaging in a cool, dry place away from direct sunlight, heat sources, and ozone-generating equipment, our gasket tape has a shelf life of 24 months from the date of manufacture. Ideal storage temperature is between 15°C and 25°C (59°F - 77°F). Do not store under heavy weight that could cause permanent compression.
Q: Can the tape be used on dynamic or moving joints?
A: No. Kaxite Sealing gasket tape is designed exclusively for static sealing applications—where the joined surfaces do not move relative to each other. This includes pipe flanges, access covers, housings, and tank lids. It must not be used as a seal for rotating shafts, pistons, or any reciprocating or sliding motion. For dynamic seals, please inquire about our specialized rotary shaft seals or O-rings.
Q: How do I calculate how much tape I need for a project?
A: Calculate the total linear length of the gasket perimeter you need to create. For a circular flange, the length needed is π (3.14) multiplied by the mean diameter (average of inner and outer gasket diameters). Add a small amount (e.g., 50mm) for overlap/waste. Our standard rolls are 10 meters long. For large or repetitive projects, we offer bulk rolls up to 50 meters. Our online calculator tool can automate this process for you.
