Industrial Silicone O Ring Supplier India

Pune is a top automotive and engineering hub in India. It has over 4,000 manufacturing units. These include auto OEMs, pharma companies, food plants, and IT hardware makers. The Pimpri-Chinchwad-Chakan-Talegaon belt makes a large share of India’s vehicles and parts. Also, the city’s pharma and biotech areas are growing fast. Every one of these industries needs high-quality silicone O-rings for sealing. KELOR meets this need by delivering consistent quality at fair prices through our Ahmedabad network.

Silicone O-Rings for Pune’s Automotive Industry

Pune is often called the Detroit of India. The local corridor houses some of the country’s largest vehicle makers. Silicone O-rings play a key role here. They seal coolant passages, air intake systems, and sensor housings. These parts face high heat that ruins normal rubber. Below are the key auto O-ring apps we supply.

People Also Ask

What is the minimum order quantity (MOQ) for custom silicone O-rings?

Our standard MOQ is 1,000 pieces per size for custom and standard silicone O-rings. This ensures cost-effective production and shipping.

How to calculate O-ring squeeze and gland fill for industrial sealing?

O-ring squeeze is typically 10% to 30% of the cross-section. Gland fill should be around 70% to 85% to allow for fluid expansion and thermal growth.

What is the maximum continuous temperature rating for silicone O-rings?

Standard VMQ silicone O-rings can handle continuous temperatures up to 200°C (392°F), while special high-temp grades can withstand up to 300°C (572°F) for short periods.

Do you provide Material Test Certificates (MTC) and FDA compliance for silicone rings?

Yes, we provide MTCs and FDA compliance documentation for food-grade and medical-grade silicone O-rings as available from our manufacturing partners.

What is the difference between VMQ (Silicone) and FKM (Viton) O-rings for high-temp applications?

VMQ (Silicone) offers excellent extreme temperature resistance and flexibility but lacks chemical resistance to oils. FKM (Viton) handles high heat and excels in resisting aggressive chemicals, fuels, and oils.

What is the standard lead time for bulk silicone O-ring dispatch from Pune to other states?

In-stock items dispatch in 2-3 days. Custom bulk orders take 7-10 working days. Transit to other Indian states typically takes 2-4 days via express courier.

How to identify genuine food-grade and medical-grade silicone O-rings?

Genuine food-grade O-rings are typically translucent or white, odorless, and do not leave a mark when pinched. They must also come with FDA or USP Class VI certification documents.

Can silicone O-rings withstand high-pressure hydraulic and pneumatic applications?

Silicone is generally not recommended for high-pressure dynamic hydraulic seals due to its low tensile strength. It is best suited for static, low-to-medium pressure pneumatic, and temperature-critical applications.

What is the recommended shelf life and storage condition for industrial silicone O-rings?

Silicone O-rings have a shelf life of 5 to 10 years. Store them in a cool, dry place away from direct sunlight, ozone sources, and extreme temperatures to maintain their elasticity.

Do you offer reverse engineering and rapid prototyping for non-standard silicone O-rings?

Yes, we offer reverse engineering from physical samples or drawings. Rapid prototyping is available to test fit and function before full-scale bulk production begins.
