Manual sealing machines require an operator to feed and activate each seal, providing control and flexibility for small batches or varied packaging. Automatic sealing machines use mechanized systems to feed, seal, and discharge products without constant human intervention, delivering higher speed, consistency, and throughput for large-scale production.

A sealing tool can be used for crafts and fabric projects to create clean, professional edges and secure seams without fraying.

PTFE and PEEK seals perform exceptionally well in vacuum environments due to their low outgassing, high thermal stability, and strong chemical resistance. PTFE provides excellent low friction and conformability, ensuring reliable sealing even at low pressures, while PEEK offers superior mechanical strength and rigidity, making both materials ideal for demanding vacuum applications.

Spiral wound gaskets offer excellent resilience and recovery, making them suitable for fluctuating temperature and pressure conditions. They provide reliable sealing in a wide range of applications, handling aggressive media and high stresses. Their construction with alternating metal and filler layers ensures durability, blowout resistance, and easy installation, while allowing for cost-effective maintenance.

Expanded graphite gaskets provide excellent chemical resistance and thermal stability, but they come with notable limitations. They exhibit relatively low mechanical strength, making them prone to cracking or extrusion under high loads and pressure surges. In oxidizing environments, graphite begins to degrade at sustained temperatures above 450°C. The material can also adhere strongly to flange surfaces, making removal difficult and potentially damaging gasket seating areas. Creep relaxation over time may require frequent retorquing, and their brittleness demands careful handling during installation. They are not ideal for strong oxidizers or certain acidic conditions that attack graphite.

Ring joint gaskets are primarily used in high-pressure, high-temperature flange connections across the oil and gas, petrochemical, and power generation industries. Their common applications include wellhead assemblies, pipeline flanges, valves, pressure vessels, and heat exchangers, where they provide reliable sealing under extreme conditions.
