O-RING BUNA 1/4 QC COUPLER

Veloci Performance O-Rings will fit in any 1/4", 3/8", and 1/2" coupler in the U.S. Market. Veloci sells well over 100,000 o-rings per year because they are commonly lost at the worst of times. From amateurs to contract cleaners, everybody blows out o-rings, the difference is the pro's always have a few spare o-rings on hand.

Don’t get caught without a few extra o-rings on the job. A small investment makes a big difference in maintaining PSI, GPM, and safety.

Types of O-Rings:

• Buna Nitrile is a common and inexpensive compound used in o-rings found in all Veloci Performance brass couplers and should only be used in cold water applications (Maximum 250º F).
• FKM (fluoroelastomer) is a more expensive and durable compound meant for Hot Water (Maximum 450º F) applications and performs well with chemical applications. Use the FKM o-rings for replacement on stainless steel fittings.
• EDPM is a more expensive and durable compound that performs well with hot water but exceptionally with chemical applications. All Veloci Performance Stainless Steel Couplers have EDPM o-rings, although we do not sell replacements; instead, replace with FKM.
