Silicone Washer 049

$15.40 - $21.00

Silicone seals are used extensively in the food and beverage industries. Silicone seals are particularly suitable for dry, aqueous and fatty foods. These capabilities make Silicone W049 a natural choice for parts that need to succeed in these demanding environments. The Silicone W049 washers we have available are Durometer: 60° +/- 5° with a temperature operating range of -60°c to +230°C. (Continuous). Full Data sheets are available on request.

  • Ulti-Flo Silicone Washer 049

Superior temperature range: Performs well in both extremes (very cold to hot), maintaining seal integrity.

Excellent environmental resistance: Strong against UV light, ozone, weathering, which helps avoid frequent failures outdoors.

Safety & inertness: Silicone is generally safe for food and water contact, non-toxic, and won’t leach chemicals.

Flexible sealing: Silicone’s ability to compress and return aids in coping with movement, vibration, or slight misfits between valve parts.

Longer life in harsh conditions: When other washers harden, crack, or degrade, silicone tends to outlast many alternatives—good value over time.

1. What is special about a silicone washer?
Silicone washers offer excellent resistance to a wide range of temperatures—both low and high—and remain flexible, so they seal well without becoming brittle.

2. What applications are silicone washers best suited for?
They are ideal where cleanliness, food or drink contact, or high/low temperature cycling is involved, since silicone is non-toxic, inert, and retains sealing and flexibility in extreme conditions.

3. How does silicone compare to other washer materials like nitrile or EPDM?
Silicone performs better at very high or very low temperatures and has better resistance to UV, ozone, and certain chemicals. However, it may not be as abrasion-tough as certian rubber types (depending on formulation) in heavily mechanical or gritty environments.

4. Why choose a silicone washer for Cocky Valve systems?
Because it provides a reliable, long-lasting seal in demanding conditions. It helps ensure water tightness in valves, especially in setups with temperature swings, exposure, or where non-metal parts touching water must meet higher hygiene or compatibility standards.
