E99-330C43 - Miller Stainless Steel CGA 330 Nipple, 3.5 Inch Length

Precision Stainless Steel Gas Connection Component

The Miller E99-330C43 is a specialized stainless steel tailpiece designed for critical gas delivery systems utilizing the CGA 330 connection standard. In industrial and laboratory environments, the integrity of gas connections is paramount, particularly when handling the corrosive gases typically associated with CGA 330 fittings (such as Hydrogen Sulfide, Hydrogen Chloride, or Boron Trifluoride). This component is engineered to withstand the chemical aggression of these substances, preventing the material degradation, pitting, and structural failure that can occur with lesser alloys or brass components in similar service.

Measuring 3.5 inches in length, this nipple provides the necessary extension to connect regulators, manifolds, or pigtails securely to gas cylinders or supply lines. The length is optimized to allow for easy wrench access during installation while maintaining a compact profile in complex piping assemblies. The machining quality reflects Miller's commitment to industrial standards, ensuring that the sealing surface mates perfectly with the corresponding gland or seat, thereby minimizing the risk of hazardous leaks. In systems where safety protocols demand zero-leakage performance and material compatibility is non-negotiable, this stainless steel tailpiece serves as a vital link in the chain of custody for hazardous gases.

Maintenance and reliability engineers will appreciate the durability of the stainless steel construction. Unlike softer metals which may deform under repeated torque or corrode over time, this tailpiece maintains its dimensional stability and structural integrity. It is an essential replacement part for maintaining existing Miller gas equipment or for fabricating custom gas distribution manifolds requiring CGA 330 compatibility. Whether used in semiconductor manufacturing, chemical synthesis, or analytical instrumentation, the E99-330C43 delivers the performance required for high-purity and corrosive gas handling.

Proper selection of fittings is the first line of defense in gas safety. By utilizing the Miller E99-330C43, operators ensure that the wetted path of their gas system is fully compatible with the media being regulated. This tailpiece is designed to work in conjunction with a matching CGA 330 nut (sold separately) to form a complete connection assembly. Its robust design ensures long service intervals and reduces the frequency of component replacement due to corrosion or wear.
