法兰密封配件 Del-Seal™ CF Fittings

MDC Del-Seal™ CF Tube Fittings are convenient “building-block” components. They offer great flexibility in the design and construction of high and ultrahigh vacuum systems.

MDC Del-Seal™ CF fittings such as nipples, half nipples, reducer nipples, flexible nipples, elbows with 45° and 90° configurations, tees, reducer tees, crosses with four-, five- and six-way configurations, six-way cubes and multiport flange assemblies comprise the industry’s largest selection of Del-Seal™ CF fitted vacuum components. If we do not have the product you seek, custom versions of most of these components can be quoted upon request.

All fittings are fabricated from type 304 stainless steel drawn and welded vacuum tubing. To facilitate assembly alignment, a rotatable flange is supplied opposite a nonrotatable flange on each axis. Elbows are supplied with two rotatable flanges.

In general, reducers are used for a change in size of flanges within a single method of sealing, such as Del-Seal™ CF to Del-Seal™ CF. Reducers may be either zero length or include a section of tubing between flanges.

Non-zero-length reducers are also called nipple reducers and have either a straight tube or a conical section between flanges.

In general, hybrid adapters provide a transition between two different methods of creating a vacuum seal, such as metal seal CF to elastomer seal ISO. Common configurations of Del-Seal™ CF to various other vacuum connections are listed in Hybrid Adapters section

Reducing tees and crosses have a single main tube with main flanges and a smaller diameter reducer tube with a reducer flange or flanges.
